Mystery of the Yetis
In the Embers of Rage campaign, the quest Mystery of the Yetis can be started either be obtaining a Yeti muscle tissue sample, or by talking to the Old Psi-Machine.
In the Ruins of a lost city in the Embers of Rage campaign, there is an Old Psi-Machine on the bottom floor. If you speak with it, it will task you with retrieving Yeti muscle tissue samples from powerful specimens, and will reward you with knowledge in exchange for them. This quest is the Embers of Rage counterpart to the Escort quests from the Age of Ascendancy and Infinite Dungeon campaigns.
