figured since we have a Hero list, why not get a Villain list too, right?

Other notables: The Ennead have a variety of people, so it's listed as "Variable" to sow they all aren't the same height. Akash'Bhuta also is listed as varies, with cards showing her going from ~6' (holding up Argent Adept slightly abover her eyeline, but quite off his feet) to the size of a mountain. Then there's Gloomweaver, who is bound within the Realm of Discord, and with a "none" listed under weight, gives me the impression of spirit-shenanigans
