Kartia Researcher:
You've heard of Dimensional Rifts, I'm assuming. How outside of the physical world we inhabit there are still other dimensions?
Of course the dimensions were kept apart to keep them from interfering with one another.
Ever since Shilen's rising however the balance has been completely thrown off. As for Kartia's Labyrinth, we've discovered that she built it specifically as a stronghold amongst the dimensional rifts, guarded by three hand-picked demons.
