I'm gonna have to side with Kho on this one, Lifprasil's entire mortal army caps out at 100,000 currently, with a soon-to-be division of 5,000 Cosmic Knights; meaning he has more than enough manpower to sling around a massive stick. In comparison, Rome had an army the size of 450,000 men at its peak, which is where I'm mostly drawing inspiration for Alefpria from.

EDIT: To emphasize, most of Lifprasil's army is currently on inactive duty, his active forces cap out at 30,000, most of which are going to be fielded in the Xerxes battle.
