The Secret Cities
Legends tell of a number of Secret Cities located throughout the multiverse that hold fragments of the meaning of existence. Loremasters from the various Shifter tribes and a number of monasteries and wizardly colleges disagree on how many Secret Cities there actually are, but they all agree that should one ever travel to all of these cities and gain their knowledge they would theoretically transcend to a higher state of life, being able to see and affect the inner workings of life and death, and possibly time itself. Balthasar, the resident wizard of the Radiant Tower in Hallowgaard has uncovered the names of 3 of these cities: The City Within the Song, The City Behind the Moon, and The City Under the Maelstrom.
The locations of these cities remain a mystery and it must be noted that the ancients had a predilection for prepositions, so any reference to locations should not be taken literally.
