Once there was island nation called Potamus, where the trees grew short and stout and the residents lived on seaweed. The island was volcanic, and frequent eruptions of hot gas singed the treetops and forced the rain forest to grow out rather than up. The volcano was only middle-aged and mostly friendly. It still lay low in the center of the island rather than a mountain looming high over it. It would remain so for centuries to come for it was content to bubble and puff rather than build itself up with lava at the cost of destruction of life on the ring of land.

The creatures who lived on Potamus were gray and bulbus, with long tubular noses.
