Femto

Femto is a mysterious red material that fell to the world during the Moonfall.

Background
Femto fell to the planet when the moon broke apart during the Moonfall. Femto particles pervade the Oval Link, and are oftentimes dense enough to be visible to the naked eye by turning the color of the air red.

In affected areas, Femto can be so dense that crystals form on surfaces. These crystals vary widely in size; some may be in small batches about the height of a human, while others are so large as to radically alter the geography of an area.

Humans and Outers
Femto is harmful, if not fatal, to most humans. Outer Syndrome is an illness presumably caused by exposure to the material.

Outers, on the other hand, are humans who have adapted to Femto. Outers possess special abilities that allow them to perform various extreme feats not possible by ordinary humans.
