Spirit Stone of Anath'Lan

The Spirit Stone of Anath'Lan is an Eldar artefact.^[1]

Anath'lan was once one of Biel-Tan Craftworld's most skilled Farseers. However, pride caused him to misread runes, dooming a Maiden World to a bitter demise. Unable to forgive himself, Anath'lan died of grief and his Spirit Stone refused to bond with the Infinity Circuit. To this day, his Spirit Stone guides other Biel-Tan Eldar away from the error that led to the Farseer's own disgrace.^[1]
