Mundus Deus (NSFW, Visions, souls and airships)

A moon to orbit the world below.
Some land for things other than fish to live.
Some grass, bushes, and trees.
And a very peculiar entity.
*Said entity is a denizen of the world, and appropriately small

SpoilerShow

The entity is short and thin, an eye on its torso and no head. Its arms and legs end at a sharp point. It's left arm would have two points, with two joints each. It's limbs are particularly long, with three joints. It does not need to eat or drink, and is aware of where the cube is if it concentrates. It's default name is Ned, but if it decides it wishes a different name, it can choose one.
