Mani's Caves were a formation of caverns in the Beor Mountains where wild magic caused strange phenomenna.
Dreams[]
Dreams in Mani's Caves are strange and wonderful, sometimes premonitions, sometimes alternate histories. It is, like the Jewel at Eoam on Beirland, an example of raw magic. There are others.
Name[]
It may be worth noting that Mani is the Old Norse (the language upon which the Ancient Language is based) name for the Moon. Whether this means anything or not is uncertain.
