Zero tumbled through the other side of the gate and landed with a heavy oof. He didn't know which part of the library that door-gate took him to but he knew for sure for a fact that the world he was seeing wasn't in the right orientation.
It took Zero a few clumsy attempts to right himself. Landing with his butt in the air on his back upside down while crashing into a wall isn't the best landing position. Zero adjusted a few kinks and tested his joints before studying the new area. This room didn't have any windows or furniture. It only had some light emitting crystals hanging from the ceiling and another door to his left, adjacent to the door he exited from. This new door didn't have keyholes so Zero put the key away into his inventory and opened it.
