The asari ark, the Leusinia, is still missing. Given Cora's history with asari commandos, she has spearheaded the effort to find the Leusinia and bring it home to the Nexus.

This is Cora's loyalty mission.


After completing Cora Harper: Asari Ark and visiting Kadara Port, returning to the Tempest and walking near the email console will prompt this mission to begin.


Read e-mail from CoraEdit

Acknowledge it to get the next objective. This can be skipped by talking to Cora before reading the email, which will mark this goal as failed but have no other effect.

The asari ark

To: Ryder
From: Cora

Had a breakthrough on the location of the asari ark. Please, come talk to me on the Tempest ASAP.


Speak to Cora on the Tempest Edit

She has tracked down the ark and has a navpoint that might be close to the ark's location. The Valay system now becomes available on the Galaxy Map.

Search the Valay system for Ark Leusinia Edit

Upon entering the Valay system, Suvi detects an anomaly on sensors. Scanning the anomaly reveals that Ark Leusinia is here, heavily damaged and nearly without power. Boarding the Leusinia begins the mission. As usual with loyalty missions, manual saving will be disabled for the duration of the mission.



Reach the bridge Edit

The party enters the Leusinia through a darkened corridor with signs of recent combat. As the party approaches the second door, Captain Atandra is heard over comms, preparing to vent the corridor to space. After convincing her that they're not more invading kett, Ryder and party are invited to the bridge. Datapads in the next area reveal details of the near-catastrophic damage to the Leusinia, and that the asari pathfinder who is now Sarissa Theris, not Matriarch Ishara overrode her SAM's recommendation, ordering the revival of the family members of the few surviving flight crew before reviving more critical personnel.

Upon reaching the bridge, Ryder finds Sarissa and Captain Atandra. Captain Atandra reveals that Matriarch Ishara died attempting to negotiate with the kett, and Sarissa being next in line for succession assumed the position of Pathfinder. Ishara's death is said to have provoked Sarissa into stealing the kett navigational charts of the Scourge. In turn, the Archon has sent his top agent, the Valiant, and his Decimation hunters in pursuit of the Leusinia, and Sarissa in particular. Kett have boarded the Leusinia and are still trapped below decks.

The Leusinia's drive core is without power, so the ark can't escape from the kett pursuers via FTL. Sarissa has her commandos attempting to repower the core, but this requires fighting the kett boarders. Ryder goes to assist them while Sarissa continues working to decipher the kett nav chart so the Leusinia can escape through the Scourge.

Look for asari commandos in Hangar Control Edit

Following a short tram ride, Ryder emerges in a corridor leading to Hangar Control. Sarissa's new second-in-command Vederia Damali is within. Vederia has discovered that the kett have blocked open the hangar doors, and the safeties are draining too much power trying to close the doors again for the drive core to recharge. 

Activate hangar door override Edit

Ryder must now use SAM on a nearby console to override the hangar door controls and stop the power drain. Interacting with the console triggers a kett attack from the catwalks above, with Ryder confined to the space near the console until the override is completed. Fortunately, there is convenient cover. After the override is finished, defeat all remaining kett to proceed.

Speak to Vederia Edit

After combat is over some power junctions to the west explode, and Vederia runs off to investigate a maintenance panel there. Follow and talk to her. Vederia discovers that something unknown in the lower decks is also draining massive amounts of power, which caused the overload and a fire below. Vederia heads off to check on the remaining stasis pods while Ryder cuts through the Leusinia's living quarters to reach the second power drain.

You receive 290 XP.

Go below decks through the living quarters Edit

As Ryder travels through the next few areas you'll occasionally hear from Vederia, who is having her own problems and receives advice from Cora.

In the next area Ryder will discover animal storage crates, which the kett apparently used to bring Wraiths aboard, and a datapad with evacuation orders. Proceed through a darkened corridor. The rooms to the side of the corridor are asari quarters and contain squadmate conversations, datapads, terminals, and minor loot; the last room contains a few Chosen. A few Wraiths will also jump you during the trip. Descending further brings Ryder to Fire Control.

Secure Fire Control Edit

Kett are here, specifically Chosen, Wraiths, and one Destined. Defeat them and use the console to attempt to activate the fire suppression system, though the console promptly shorts out. Scanning reveals a nearby access panel where power has been diverted someplace else. Interact with the panel and then use the console again. This activates the fire suppression system and Ryder may proceed.

At this point, Vederia calls Ryder and says that she's discovered the source of the second power drain. She gives Ryder the nav point and heads off to meet them there.

You receive 290 XP.

Meet Vederia Edit

Proceed through a door which was previously blocked by the fire. At the bottom of the stairs, if you continue past the stairs leading to the objective marker, you'll find engineer Lapiris T'Caal's lab. A datapad and scannable object here offer some insight into the mysterious power drain ahead.

Proceed to the Observation Deck. Vederia is here, with a device which proves to be a mass effect generator used to hold a large section of damaged hull plating in place, which kept enough air pressure for a hundred asari to escape. Now the power drain is keeping the Leusinia from going to FTL. Vederia can't shut the device down, and needs Ryder's and SAM's assistance.

Scanning the device reveals that disconnecting the three power cables will require one person to work on the device while another works on the power connections. Otherwise the device will "fuse", which is apparently a bad thing. Vederia will stay at the device while Ryder works on the connections, which are now marked as nav points.

Disconnect power cables Edit

As Ryder disconnects each cable, a wave of kett -- one Destined, one Anointed, and several Chosen and Wraiths -- drops in to attack you. Dispatch each wave and proceed to the next cable. Kett will shoot at Vederia, but her biotic barrier seems to be invincible.

Once the final wave is defeated (580 XP), return to the device and deactivate it.

Deactivating the device releases the section of hull plating, and enough power to charge the FTL drive. As Vederia runs off to assist, SAM locates Matriarch Ishara's succession log, which is now accessible thanks to the restored power. The audio log reveals that Ishara died because Sarissa chose to go after the kett navigational charts rather than to rescue her Pathfinder. Cora is distraught; Ryder can either agree with Sarissa's decision or call it a screwup.

The kett interrupt the conversation by sending a dropship to the hull breach on deck 12. Sarissa comes down from the bridge to assist, while Ryder and squadmates put on their helmets and head for the breach.

Repel the kett attack on Deck Twelve Edit

As Ryder proceeds to the breach, SAM informs Ryder that the mass effect field device can still be used to disrupt local gravity. 

You're going to face three kett waves here, composed of multiple Destined, Anointed, and Chosen. The Valiant, an Ascendant, will personally join the third wave. The console in the middle of the balcony on the middle level can be used to trigger the mass effect device. Triggering it will blow most of the kett in a wave into space (though not the Valiant), while Ryder and company are secured by their mag boots. The device will only work once, so you'll probably want to save it  for the third wave so you can concentrate on the Valiant. Note that enemies can be tossed out of the hull breach by Throw and similar powers.

Defeating the Valiant triggers a cutscene where the wounded Valiant orders his ship to forget about capturing the Ark and destroy it instead. At this point Sarissa finally arrives and finishes him off. The Valiant's ship now launches a barrage of missiles at the Leusinia, but Sarissa, assisted by Cora, forms a large Barrier which deflects most of the missiles and reflects others back at the Valiant's ship, which explodes as the Leusinia escapes into FTL.

Note: When then Valiant is defeated you receive a large amount of XP. It can't be seen on the screen because the cutscene starts immediately. You notice it if you get a level up message.

Decide Sarissa's fate Edit

Ryder, Cora, and Sarissa return to the bridge and meet up with Captain Atandra and Vederia. Ryder and Cora confront Sarissa about Matriarch Ishara's death. Sarissa wants her actions covered up, saying that a Pathfinder needs to give the people hope. Ryder can either go along with the coverup or demand that the truth be told.

If Ryder doesn't go along with the coverup, Captain Atandra is furious with Sarissa and wants to transfer Pathfinder status to the next in line, who is Vederia. Ryder can either agree to this or advise that Sarissa be kept as Pathfinder.

If Ryder both exposes Sarissa's action and goes along with Atandra, Vederia replaces Sarissa as the asari pathfinder. Otherwise, Sarissa keeps the job. While Cora is not happy with a coverup, there don't seem to be any serious repercussions for her relationship with Ryder, whatever is chosen.

Aftermath Edit

Ark Leusinia will now be docked at the Nexus. Next time Ryder visits the Nexus the asari are welcomed by Tann, and they also give their thanks to Ryder for saving them.

If you choose to keep Sarissa’s actions a secret or allow her to stay on as Pathfinder, she shows up in the game's final battle. If you replace Sarissa with Vederia, Vederia shows up instead.

Cora's rank 6 skills are unlocked.

Deck 12 hull plating sheared. Atmosphere was vented. No time or personnel to weld.
100+ trapped. No suits. No time. Can't be done.
CAN BE DONE. No one else dies today.
Want to grab the kett by the throat and shake them. Keep dreaming, skinny. Should've been a huntress.
Grab. GRAB. Hold the deck plating in place. Not airtight but enough for breathers. Solved!

From: Thanamis T'Jotra

Forward to anyone not on the main list:

Belas: I can take the twins and Mohia tonight. We're camped by the emergency lighting so Mohia will have her night-light.
Jodiri: Because the T'Kastes and Zahlie got called for evac early, there's leftover cleanup supplies and food in the red cooler.
Remember, if you need diaper bags, there's sterile cleanup bags in the washroom cabinets. Break the locks if you have to.

Day ten, still going strong.

Making the big jump soon. Leaving all my love and best wishes. Go ahead and share out my stasis locker. Can't take it, can't worry about it.

We'll find help, promise.

What's Happening
To: Ark Leusinia: All
From: Sarissa Theris

You're out of stasis because you were needed on deck early. Unfortunately, you now need to adapt to a very different scenario than was expected. To avoid rumors spreading, this is the situation:

- We are under attack by a hostile species. Diplomatic overtures were rejected and will not be repeated.
- Regrettably, our Matriarch Ishara died attempting negotiations. I have reluctantly taken on her role as Pathfinder, but cannot replace her.
- We must deviate from our intended course and attempt to lose the enemy before our rendezvous with the Nexus.

With Captain Atandra's approval, I've authorized a general evacuation order as we revive civilians. Meanwhile, commando forces and our survey ship, the Periphona, will perform necessary diversionary actions.

I will not understate the seriousness of our position. I won't underestimate your skills, either. I have faith in you.

For the last time, I'm not shutting up! I went to sleep dreaming of new worlds and woke to fire and screaming and people huddled in dormitories. And they won't let us back into stasis! We're supposed to just crash-land on a barren planet in some teeny escape pod, like that's going to be better?

I want what was promised, what I gave them my money and my LIFE for, and I'm not going to stop trying to get answers!

To: Thella Ranthius
From: Giona Jeden

Comms still down, doing this the old-fashioned way. We CANNOT finish the evac with Deck 12 in that condition. That last kett barrage sheared the hull plating--no atmosphere and it's hanging by a thread. I've got a hundred people trapped on the other side and not enough suits. There's children.

Thel, I can't make that call. I won't.



Re: Evac

Lapiris just showed up. That screwball engineer refused her evacuation seat. Says she's got an idea.

To: Ark Leusinia: Maintenance
From: Lieutenant Kolona T'Jaxan
Headed off-ark soon to give those kett something to chase. Our gear got shot to shit in the last encounter, but old habits made me stick it all in recharge.

Do me a favor and keep it away from the civvis, would you? No sense someone coming all this way and then shooting themselves in the foot.
