Tomes in Amber
There is little convincing evidence that the Zithin Empire is anything more than pseudo-academic fantasy. Some human scholars believe that several thousand years ago a race of humanoids ruled the entire continent. The copper mines of Galadale have been purported to possess tunnels that reach ruins from this ancient civilization but there has been no official exploring done.
Legends of the Zithin Empire tell of a magical race who, at the zenith of their power had mastery over death. Though the lack of any living Zithin is widely considered to support the “legend” status of such claims.
