Kael said:There are 2 kinds of demons. The most powerful were lesser angels in the service of the 8 angels/gods that fell. The less powerful were once mortal's whose souls have become corrupted. From the lowest Mares, to Imps (mages who have traded their soul for power), to the Sect of Flies (false prophets), to the Ruhin (betrayers).
To give you some indication of the power level the Balor are the weakest of the "true" demons (those that were never mortal).
There are the "low" demons (ex-mortals) and "true" demons (nevermortals)
What are these groups called? Corrupt/fallen souls and fallen angels?
What are Balors? I heard they formed from Agares's darkness and Bhall's fire on their border, but thus they aren't fallen angels but something else...
