Story
Amunta is being held in a grotto not far from the hideout. You decided to rescue him on behalf of the injured Umbaba and the Daybreak Society. Umbaba informed you of Muqaka's search parties and asked you to protect Amunta. Amunta seems to be a deeply respected leader, or perhaps his meaning to the Society members is even deeper.

"Us Mau... We've always revered the Balaur, but this is far beyond admiration." You found Ritualist Amunta in the Prisoners Grotto. He had been weakened by torture, but his spirits remains strong.
