The Ancient Chaos force snrked awake... it doesn't know how long it's been asleep... but it's undoubtedly been long enough that his ancient foe of order had managed to wipe clean whatever fun it had had last time... until it got bored... but that was just fine by it... things had gotten too.... ordered for it, as it always does, causing the chaotic force to lose interest leaving the world to sort itself out.
But now it's been long enough that it could enjoy it's fun all over again in any new and interesting way it could think of... this was going to be fun all over again...
