Ephya Crusade

The Ephya Crusade was a campaign of conquest led by Thayrus from -8773 to -6961. The demons launched their invasions in a desire to accumulate more power and the elimination of possible future threats. The conflict resulted in the death of several prominent figures of each side, including that of Thayrus, several major gods, and realms that had been absorbed into Anelom.

Background
Centuries before the beginning of the Crusade, Thayrus began to gather the souls of mortals to convert into soldiers for his war. This process brought entire legions of demons into the fold, although weaker, they would provide a steady stream of cannon fodder. As this Crusade had the potential of gaining a net positive for the Demon Lords, many were enthusiastic and willingly contributed. Despite the enthusiasm, the various Demon Lords were still within conflict with one another from time to time.

Many realms became complacent towards the demons due to the false information coming out of Anelom, with most believing them deep in a civil war among themselves (although true, it was not to the extent many believed). Thus, many were soon to be taken by surprise at the sudden cohesion of the demon's legions.
