Actually, I'd say that any mage powerful enough is potentially an Evanuris, regardless of race: if you look at the process that led Elven mages to be remembered as gods, it's actually very similar to what we had in real life:
- Powerful Mages victorious in war became elder statesmen, then royalty, then demanded -and obtained- worship.
- Powerful warlords victorious in wars become rulers, start their dynasty, and eventually come up with stuff like the Divine Right of Kings or the Mandate of Heaven or the "We are the Avatar/Reincarnation of Gods" excuse to justify religiously their bloodlines' ongoing rule.
The Evanuris' (Evanurises? Is there a plural form for the term) specificity being that they were immortal, which gave them time to increase their mastery of magic to civilization-shaping levels but more importantly allowed their rule to go from "leadership by victorious generals" to "rule of decadent god-kings" without going through the dynastic phase.
The mage Warden, mage Hawke, mage Inquisitor, already completed the first steps toward Evanuris status: they all were instrumental in winning wars they fought at the forefront (Blight, Qunari invasion, War against Corypheus), and they all achieved Elder statesman status (Arl(esa) of Amaranthine, Champion of Kirkwall, leader of the Inquisition), the only difference being that since they are mortals, none has the time to go through the long process of "ascending" to Godhood through centuries of unbroken rule.
