What happened without seeming to have an end, there were for eons, the isolated conflicts between rebellions, taking place between the so-called blood wars.
They were battles that grew, leading the isolated conflicts between the celestial forces and the infernal forces to enter into an eternal war that caused several worlds to come to an end, leading several worlds to ruins.
Happening without really ending, neither side overcoming the other, for countless ages, causing the end of many races and civilizations.
In search of allies and new forces each side converted several other races into war, in the midst of this, there were countless casualties on both sides, when the demonic and celestial forces could not win, they found ways to get followers amid the wars that seemed to have no end.
