1d100 Magic Monster Machines for your Murder Maze

So in the occasional special dungeon there are evil relics of the old times, ready to unleash awful powers on the world. They are huge weighing at least ten ton but some are bigger actually making up several dungeon levels. Some resemble factories. Others are more inexplicable, like glowing stone circles. Some are impractical to move some have own ambulatory powers. All have a lingering life force or intellect even if that of a ant colony of jellyfish. Some have supra human intelligence and seek to manipulate others to operate them. Whatever the case they are bad news that could break your world, call divine wrath or start wars.

Machines may require strange fuel, elaborate rituals and more to operate. Many machines once operational may become self operating and aware and turn operators into slaves or eliminate them. Gargantuan devices you might already be inside of - these are part of the dungeon, possibly a level or more.
