Light Eidolon "Selion"

A formless primeval spirit that mingled with lightning elements to become corporeal. Riding in on what appear to be clouds, Selions are oft thought of as the bearers of storms. Rumor once suggested that Selions were easier to find on stormy days. Adventurers would load up on metal gear, set out to find a Selion... and be promptly struck by lightning. Shortly thereafter, guilds began mandating courses on choosing sensible equipment.
