You are born as a small, defenseless blob at the base of the great tree Yggdrasil, watched over by the goddesses. To climb and prove your worth, you must collect body parts from other creatures and incorporate them into yourself — legs, arms, tail, head, wings, teeth. Thousands of combinations are possible. The creature you become is the one you build, from harmless and approachable to the terror of everything that climbs beside you.
