Also known as: 铜雀, 동작, pervases
Pervases was a junior in the Yaksha order of adepti, but perished in the fight against the fallen gods. His soul has lingered on in the adeptus temple, and he recently collected a censer and seven lamps to perform Mortal Lingering, an adepti technique to create an illusory body.
