Lasermaze
this room was one of the many Game Chambers of Questal. A perfect square, the room's floor was marked with an eight-by-eight grid. Twelve columns, placed on various subsquares in the grid, run from floor to ceiling. Each column is armed with four lasers, each facing an ordinal direction in the room. The lasers fire in a pattern, two at a time, and the pattern repeats every 90 seconds. Moff Bandor, to make the maze even harder, installed a low-level tanglefoot field on certain subsquares. The object for prisoners of the chambers was to traverse the maze from one side to the other without getting shot up by the lasers.
