Drow of the house Alendar
Jalrayna was a drow of the house of Alendar, and a member of the Felsworn. She was the drow who had the most direct contact with the humans of Madaban, as she was tasked with bringing soul gems from there to the center of her house’s power. She was about as one would expect from a drow, and she stabbed the party in the back at least once. She was most likely killed when house Alendar’s fortress was removed from the map, but her corpse was never seen, so you never know.
