72 WORM GATE. This portcullis is made of strong iron bars decorated with writhing and crawling worms. One bar is thicker than the others. It holds a key-hole, and if the key is inserted, mechanisms inside will cause the portcullis to raise. It is kept oiled and will not attract wandering monsters. It can also be opened by a knock spell or other magic. If forced (bend bars/lift gates roll) or broken down by force, it will call for an immediate wandering monsters check.
