Eidolons are one of the Servant races created by Koss from the White Flame of UN.[2]
Description[]
Eidolons are the primary servant race of the craft and the forge. The craft God Koss, whose corpse can be found hunched over the Concordance of Angels, was said to have cried a single teardrop in his entire life. This massive teardrop crystalized as it fell and split into ten thousand fragments, which he used to make stone beings to help him at his forge.[2]
The true form of an eidolon is a holy symbol of soul-fire – it can usually only be seen in very dark or dim light. It resides in the hole inside their crystalline ‘heads’, sustained by the crystal around it. An eidolon can survive as long as its crystal is intact, and their stone bodies are artificial – it is not unusual for eidolons to forge or commission new ones.[2]
Even more unusual are eidolons that share a body or crystal – two- or even three-souled eidolons are not uncommon. This is suspected to be part of eidolon reproduction – it is known that their crystals grow in size as they age – but its true nature will likely never be revealed, as eidolons consider it a holy secret.[2]
Omun Vash's favourite guard in the Golden Pearl Pleasure Guild was an eidolon who served him alongside his brother.[1]
Trivia[]
Their design is likely inspired by adder stones, or hag stones. These are naturally occurring stones with holes through them, and often are assigned spiritual or folk-religious importance.
