Blood Void Energy is a horrible variation on Void power. Blood Void is an energy that seeks to consume all around it and remove existence itself. Those consumed by its power actively seek dissolution of themselves and all around them. However, even that which is obliviated can be recovered if the memory of it survives. Blood Void Energy is extremely, extremely rare, even in fiction: it's frightening to even write about. If anything can unite nearly the whole multiverse, it is opposing this force.
