Servants of Morpheus, Loki, and other mind-related gods, the Idolon are powerful psionic entities. Rarely seen on Earth, they have an unknown agenda which seems to be either disruptive or supportive of the goals of the characters, depending on whom they serve.
Idolon are cyan humanoids with large heads, which hold large brains that are the source of there overt psionic abilities. Unlike other familiars, they are entirely wingless, using their telekinetic abilities to levitate and fly. They prefer to use their natural abilities than employ magic, but idolon mages are not uncommon in their race.
Their telepathic network gives them a strict, hivemind-like hierarchy, but each individual has a distinct personality and independence of their own.
