Yuttos are Shadowlands natives, followers of Ergo (manifested as the stone face seen when first entering), who sets himself between the Redeemed and the Unredeemed in a position of neutrality and preserver of the balance.
Yuttos in the Shadowlands are on the whole a benign influence, acting as guides, contact NPCs for quests, and merchants for useful items such as higher Quality Levels of Semi-Finished First-Aid Kits.
On Rubi-Ka, they play a much smaller role in the storyline. They live in a few of the more remote areas of RK, distanced from its residents, and show no aggression until attacked.
Weapon QL equals the creature lvl.
