About the speculation...
Isn't it rather far fetched? Diablo and his brothers were spawned in the Abyss. And I don't think demons will be happy to let former Archangels rule them. Also, the lore states that from time immemorial, The High Heavens and The Burning Hells have been in conflict.--TheWanderer 05:16, 25 September 2009 (CEST)
- The speculation involves only whether Mirakodus was the former name of Diablo, not whether he used to be an angel. Whether he was an angel or not completely depends on if Diablo: Demonsbane is canonical or not. If it is, then we KNOW Diablo used to be an angel, likely an Archangel. If not, then we can remove the speculation section. --Leord 12:53, 25 September 2009 (CEST)
