aka: Ancient Lord of Dreams
Vagary is an Ancient Beast that was found in an ancient forest at the Lesser Wyrmcircle in Aensdoun by Opus, Bastion and Dr. Nefirian Dreamscar. It looks somewhat like a chimaera, maybe even a predecessor. It has an extremely powerful ancient aura and is about 50 feet high; it also seems to be studded with mirajin crystals.
It seems it has slept for centuries and has recently woken up, and may be what caused the mirajin anomalies.
