Smoolon

Smoolon is the fifth planet in the Smootian system. It is described as "poor in resources, miserable in climate, and shrouded with noxious fog". It is the home planet of the Smoolonians.

According to Yop, the ancient legends of the Smoolonians speak of a time when Smoolon was much more pleasant. According to these legends, the Smootians used their geomorphic transporters to move Smoolon farther away from their sun, in order to make room for Smoo.
