There was something that caused them to come here this quickly and if I had to guess, then I would have to say that it was me.
In my last life. I only managed to get one of the fragments that I was supposed to collect. I wasn't the one that dealt with the Lich and Treant, so other people got those fragments and then Kyle was also with another fragment. I only managed to get one fragment and that was when the war already began. I never even got to know what the fragments could do when they were all gathered. All I know is that they were connected to the many disasters that happened in the tower.
But since I was now collecting all of the fragments alone and I was almost done getting all of them, the invasion was moved up. This was the only sensible explanation that I could come up with as to why the monsters were already here.
