Very cool hook, very creatively designed! Spelling errors and mistakes throughout, but a great premise that strongly sat with me. I love the idea of equipment randomly being switched between universes and the idea of Sycorax hijacking the tower. Gravity shifting is a fun idea too.
Considering its your first attempt by the sounds of things, a pretty good showing! Work on the spelling and grammar and you'll have a really solid little module on your hands, here.
