The Saga of Darren Shan/WMG

The Demonata and the saga of Darren Shan share the same universe.
Ok I like to think that Darren Shan's two series share the same universe. This would mean that Mr Tiny is a demon possibly a Demon Master. The Wolf Man is a werewolf like in the Demonata and that bit in the last book s well. Or maybe.
 * I'm pretty sure Lord Loss isn't really bound by any sort of laws of reality. However, everything else would be plausible, if it weren't for the fact that there are no demons there. Evanna talks of them crossing over if the laws of the universe are broken. In fact, not only that but it's implied that once this happens they'll slaughter everyone everywhere. Not exactly what happens in the Demonata. (Although I suppose what happened in Bec's time seems similar.)
 * The demons certainly do try to slaughter everyone they see, but the difficulty in crossing over allows for the Disciples to stop them before they manage to cause too much trouble. Should the laws of reality break to the point where the demons can freely cross over, it would be little trouble for them to win the ensuing war. Keep in mind, some demons are the size of small countries. Just the impact of one teleporting in over the planet and falling would cause massive devastation, let alone if it could fight.

The Saga of Darren Shan takes place in our reality.
At the end of the series,  This implies that not only is the story taking place in our universe (where it was published), but that the war might be occurring right now....
