Townsend Island

Townsend Island is the biggest island in the Floating Islands. It contains Townsend City where the Sadistas, a subspecies of Humans live. The city takes up almost the whole island except for the River, Fisher Forest, Church, and Champion's Castle.

Background
Townsend Island is thought to be where the Floating Islands started with each island breaking of from it.

It is big enough to have a small gravitational pull keeping the other islands in place so they won't drift off any further.
