Useful Vocabulary

Alchemist: Are individuals born with potential for magic, who got basic education in it and reached the level where they could do the First Test, but completely failed this test. They have the magic potential awaken, but burned. Consequence is that they cannot make spells or use Xar in any way by themselves, but unlike those who have no magic potential awaken they can use the spells in magic tools and weapons, and they also are more easily affected by magic potions and elixires.                                Energetic Perimeter or EP: Magic Procedure employed by most mages and sigraxes, usually founded in the mages specific Way and complemented by adicional spells. Is a defensive procedure sufficient to stop any non-magical attack, which works even when the magic user is sleeping or distracted, and includes a counter attack immediate. Once activated the magic user has no control over the Perimeter, the counter attack happens and the Energetic Perimeter looses almost all its power, needing to be recharged.                              Sigraxes only keep one EP at the time, but mages frequently overlap layers and more layers of that protection, each one at least as powerful as the best defense a sigrax can dream about.     
Hydrous: category of classification in biology, equivalent to mammal (according to most Scholar Castes, but some suggest it should rater be equated to vertebrate). Hydrous are animals whit all their body in liquid state (perfect or true hydrous) or part of it in that state (imperfect or false hydrous) and just a few solid organs. Those animals have greater control over their shape than solid ones, without the need of magic that characterize the were-species. Most of such animals cannot simulate solid state, but some (particularly false hydrous) can not only simulate flesh and teeth, but even would or stone.
Involuntary Immigrant, or ii : term used for those who arrived to Sharitarn from parallel planets, brought by the Vortex. Usually it refers to intelligent (talking) species but can be also used to non-talking ones. All intelligent species on Sharitarn are iis, except for the humans (and less common cases of species created or manipulated by magic on Sharitarn).
Mages: individuals born with magic potential, who entered a Magic University and reached the point where they could make the First Test, succeeded the First Test with flying colors gaining the right to continue the studies, reached the Second Test and succeeded it as well. Most mages are humans, because humanity controls the Magic Universities, and only in them is possible to reach the Second Test. While sigraxes are closer to the typical level of power "mages" usually have in medieval fantasy the mages of Sharitarn are walking nuclear bombs, about what you would expect of a Deity in Dungeons and Dragons (except that they are physical beings who age and eventually die, generally speaking).     

Merchant Language: the "global language" on Sharitarn. Not everyone speaks it, but those who deal with people from other nations in regular basis do.
Path: the equivalent of magic Way, a tradition or school of magic, but one that does not work according to the same structural logic of magical Ways. Being less than entirely compatible whit the core nature of magic in Sharitarn Universe Paths end up being less powerful (generally speaking) than the Ways. What does not exclude the possibility of a particular sorcerer, witch, shaman or warlock prevail against a particular sigrax under specific circumstances.
Sigrax (or false mage): are individuals born with magic potential who got basic education in a Magic University and reached the level where they could do the First Test, succeeded in this test but with mediocre results. Or, they got their education from a wild sigrax, in a traditional master-disciple relation. Unworthy of continue their formation (being in a University) or having reached the apex of it (being wild sigrax) the disciple who reaches the level of sigrax is a magic user, but will never reach the amazing powers of a mage. 
Squirrelmen: a elite warrior who fights mounted on a squirrel, in so perfect harmony with his beast that they are said to be one spirit in two bodies. Squirrelmen are all but entirely unknow outside the Grey Snake formation, but they are extremely respected inside that area.
Vortex : natural phenomenon that captures objects, animals and people from universes identical in Astronomic Scale and deposits them on the universe of Sharitarn. Only one planet is affected in each Universe, the one that is parallel to planet Sharitarn (in our case, planet Earth). The phenomenon leaves no traces of is activity in the parallel universes, except for the absence of those it has caught, registers and personal memories of it are erased with the disappearance of the whirlwind.
Way: in the sense of "Magical Way" the expression is always capitalized. Ways are the magic schools on Sharitarn, all spells are created in some Way and must follow the principles of that to function (save for a handful of "almost spells" classified as metamagic tools). Magic users can only learn the basic, and weaker, spells of most Ways. To advance above that the practitioner must line his magical body with the Way (a irreversible process named "follow"). Follow the Way affects a practitioner's personality and humor, even his opinions about big and small subjects in some extent. Each magic user can only follow one Way of magic. This expression is often used to differentiate someone who practices Sharitarne magic from someone who has natural magic powers linked to a parallel world. Those traditions are named Paths.
Wild Sigrax: a sigrax who was educated in a traditional master-disciple relationship, by another sigrax. They are usually less versatile and less powerful than civilized sigraxes, because their education has to include all the meta-magic skills necessary to initiate new sigraxes in individual tutelage. Wild sigraxes usually belong to barbarian tribes (human or not-human) and make oaths which include pass their knowledge and power to at least one worthy disciple and never teach anyone who isn't from their people and/or loyal to its ideals.
