Jarrod

From Mass Effect Wiki

Jarrod was one of the few krogan warlords to survive the Krogan Rebellions, and the father of Urdnot Wrex. He carried a powerful grudge against the Citadel races after the Rebellions and the devastating effects that the genophage had on his species. Disregarding the fact krogan numbers had been decimated, Jarrod -- and other tribal leaders who followed him -- intended to keep fighting no matter what.

However, other krogan leaders, including Wrex himself, refused to follow Jarrod's call to war, preferring to focus on breeding instead. Jarrod became angry, and arranged for a Crush (a meeting on neutral ground) with Wrex and other tribal leaders at the ancestral burial grounds of the Hollows, to discuss what should be done.

At the Crush, Jarrod tried to sway his son to his ideas, but Wrex insisted that the survival of their species depended on forgetting the war, and focusing on breeding, at least for one generation. When it became clear that Wrex and his followers would not listen, Jarrod gave a signal. His men -- who had been lying in wait in the Hollows' many graves -- launched their ambush and attacked Wrex and his warriors.

Wrex's men were slaughtered, and Wrex was attacked by Jarrod himself. The two krogan battled, but Wrex eventually managed to kill Jarrod by driving his dagger into his chest before escaping. Jarrod's betrayal, and his willingness to commit a forbidden act of violence at the Hollows merely to continue his vendetta against the Citadel races, opened Wrex's eyes to what his species had become, and prompted his departure from his home system.
