Tunnels & Trolls : Gristlegrim Room 131--Sandstone Arch

The room is the standard 100 foot hollow cube. The walls are a soft glowing gray. The room is completely empty except that an enormous arch of red sandstone splits it in half. Carved into the sandstone are pictures of whatever wandering monster is going to be sent from Monster Control. Once adventurers have entered this room, the only way out is through the door on the other side of the room. Passing through the arch will activate the monster summoning spell, and something will bamf in from monster control. Maybe a lot of somethings, but luckily, they will only be level one monsters. The door leading out of the room will not open until all the summoned monsters have been slain. Have a good fight!
