You do manage to squeeze into the hole, as you fall down maybe 5 feet and land on your head/shoulders. The lightening outside flashing into where ever you are, as you get your bearings and look around. From what you can tell you are in a hallway of sorts. All polished rock on all sides. The weird and interesting part is the slightly glowing lines of arcane power criss crossing all over the walls and ceiling and floor. The lines that were severed by the hole in the wall sparkling as the frayed ends give off the sparks. The hallway itself is at a slant, with one end going down at a sharp angle, with the other end doing the opposite.
