Quartermaster Istaal is an angara charged with distributing weapons for the Angaran Resistance on Aya. After Pathfinder Ryder frees the Moshae from the kett and returns to Aya with her, Evfra clears them to purchase weapons at her depot. Despite her objections to trusting an alien, she relents as she respects the Moshae and allows the Pathfinder to peruse her wares.
