Ixzan

The Ixzan was a semi-amphibious race, related in some kind with the ixitxachitl. They like ixitxachitl resembled a Demon Ray but unlike their supposed cousin they lived only in Underdark; it's strange note that even if existed salt lakes in Underdark and lakes of fresh water in surface never happened to found ixitxachitl or ixzan in the habitat of the other specie.

Among the ixzan there were two particular kind of population, mutant and vampiric. The mutant formed the 2% of ixzan population and vampiric, akin to vampiric ixitxachtl, formed some of 3%.

History
The true history of the ixzan was lost in the mists of legends. About their origin were three main theories. The most common told that the ixzan were an offshoot of the ixitxachitl, like happened to drow and duergar. The second told the opposite, there was a main race in Underdark long ago from which derived ixzan, ixitxachitl, cloakers, lurkers, mantari, miners (forest trappers), and possibly even sinisters (that many considered a kind of bat). After ixitchatchitl and miners emigrated out of Underdark, on the opposite all the other races, include ixzan, remained in the same terrain. A third hypothesis, liked by few sages, told that ixitchatchitl were from sea, after for unknown reason migrated in Underdark, here from they by cause of radiation emerged the ixzan, and after bothered by radiation Ixitxachitl come back to surface seas. Also the ixzan history after their origin was nebulous, thank to their oral transmission system and the influence of the Ilxendren clergy. Two events however were considered semi-historical by most: the Great Flood and the Revelation of Demonray. The first told that the scattered of the ixzan race happened caused by a great flood; the sages that believed this story tried to explained the flood as caused by rapid glacier melting, improvvise opened of gates to Elemental Plane of Water or sudden draining of great lakes. The second story told the apparition of god Ilxendren that unified all ixzan under his worship; before ixzan ado rated many dark power, usually Dagon, Demogorgon and even Panzuriel but after virtually all ixzan adopted the worship of Ilxendren, that also caused che come in born of the first vampiric ixzan.

Organization
The ixzan community usually were divided along caste line. Usually the young were tutored by special instructor in the way of cleric or wizard. Strange the ixzan always identified individuals with potential for magic and treasured them. Vampiric ixzan always arrived to the top of their community. Ixzan community were governed by an oligarchy of priest and wizards.

Relationship
The ixzan had virtually no natural enemy; their tendency to isolate their community usually permitted to avoid conflict with humanoid races. The ixzan were in good term only with aboleth and kuo-toa. In relation with aboleth were the aboleth to had the upper hand, with the kuo-toa were the ixzan to dominate. Many ixzan lived among kuo-toa.
