What is Fomor?

Fomor is a small, fairly useless planet in the New Caledonia system. It has no atmosphere, no resources of interest, and no features that stand out. Fomor does have one oddity: a few varieties of fungi grow on this planet that are related to other fungus found on Coal Sack planets. As the entire New Caledonian group was found to have no native life forms, how common fungi reached this planet is a cause of great debate, one with no answer in sight.
