Prologue: The Beginning
A war between Angels and Demons, oh my!...
Once, a long time ago, there was a massive war between the forces of Light and Dark. Angels and Demons battled fiercely for supremacy in a war that lasted hundreds of years. While most Demons gloried in the bloody battles, there were a few handfuls that got sick and tired of seeing their comrades fall with no way to help them. So these Demons taught themselves how to twist their Dark magic's to heal and became the first Dark Angels. Just like the Demons there were a few handfuls of Angels who got annoyed with always being on the defensive and never offensive, Angels would never attack unless attacked first. So these Angels learnt how to twist their Light magic's to kill and became the first Light Demons. With these new species the war grew, intensified and became less likely to end, until that is a stranger arrived. A stranger with the powers of a God; twin weapons of vast powers and, seemingly, a need to kill. The stranger killed indiscriminately in great numbers and all who faced him fell, killed without remorse or joy. Light Demons, Dark Angels, Angels and Demons all tried to defeat the stranger but none were successful for spells and weapons had no effect on him. So they named him Bane, for ruin/destruction/death was all he bought.
Years passed and the four species diminished more rapidly than they had before, until one bright soul of each race suggested that perhaps they should form an alliance with the other species to stop this Bane. So an alliance was formed and for the first time in hundreds of years the four races worked together for a single purpose, the end of Bane. Eventually they worked out a massive and complex spell that would work, so the four armies went to confront Bane and his weapons. When they found Bane he showed no surprise in seeing them but who knows what he was thinking for this one never showed his feelings, his eyes always remained cold and lifeless. In a fight that saw many more of their people dead the Light Demons, Dark Angels, Angels and Demons finally defeated Bane. They knew he would be back though, for before he vanished without a trace he said "Fool's, I am not so easy to dispose of and I'll be back but, unfortunately for you, I will not be easily recognized". Just as Bane disappeared a powerful spell was unleashed and swept through everyone. It was not until many years later that they found out what the spell had done.
The effects of the spell were really quite simple; the four races could no longer breed with their own species or as it turned out, each others. Instead, if they wanted to procreate they had to breed with the magical and non magical humans that came to inhabit their world. The four races still didn't age passed twenty one but now instead of living forever they died, for no apparent reason, when they hit one hundred. Another odd effect was that the only thing that could kill them was someone from either their own species or one of the other three. So the four species knew that Bane would be back but there wasn't allot they could do besides passing onto the wizards the tale of Bane and the need to be constantly on guard. Precautions were set for the return of Bane, but as we all know time has a way of losing things and things that should never, ever be forgotten fade away.
