Maduka, a ghost in Raksang, mentioned a Krall who served with him well in his living years. He had a familiar name: Ulaguru. You sought Ulaguru out in Sanctum, and passed on Maduka's message. The Krall responded by sinking into depression. When you told Mameia about this, she thanked you for giving her new information on the Krall, though she worried about Ulaguru's pride.
