Sundered Ones

Powerful but broken creatures, enslaved to keep mankind alive in the flood of Black Water. Sundered appearance is wildly varied, and they are categorized according to Tier—gauged according to similarity to humans in appearance and levels of power. Sundered Ones cannot reproduce, and the act of Claiming eventually kills them. Unfortunately, there’s no way around this; claiming and controlling Sundered Ones is the only way human still have food, water, and even electricity. Without them, the humans will die out.
