== Biases ==
Reality within individual dimensions is governed by four different ''bias'' categories: Body, Technology, Psionics, and Magic.  Every skill has a score, or ''bias level'', organized under one of the four bias categories, and every world has a bias level in each of the bias categories.  The interactions of these biases play multiple roles: modifiers on the chance of skill success, a limiter on what is possible in the current universe, a definition of what is known by the locals, a bonus or penalty to the chance to learn something new, et al.<ref name="Referee's Rules" />   The four bias categories defined below.

*''Body'' (a.k.a. 'bod') refers to bio-chemistry and organics (this includes inorganic life-forms as well), defining what is possible for organic life in a given world.  Skills of this bias include grapples, acrobatics, [[Iron Shirt]], [[bioluminescence]], [[Regeneration (biology)|regeneration]], etc.  A given world's Bod bias governs the presence and complexity of the world's chemical and/or organic inhabitants as well as the success rate of any attempted bod skills.<ref name="Referee's Rules" />
*''Technology'' (a.k.a. 'tech') refers primarily to traditional physics and the behavior of equipment and machines.  This bias governs a character's ability to operate [[simple machines]], watches, guns, lighters, power tools, mechanical vehicles, robots, etc.  A world's Tech bias governs the success rate and presence of these devices in the world.<ref name="Referee's Rules" />
*''Psionics'' (a.k.a. 'psi') refers to mental feats and psychic phenomena.  Lower level examples are language, decoding, standard cognition, and metacognition.  Higher level psi skills include [[Extrasensory perception|ESP]], [[telepathy]], [[pyrokinetic]]s, [[telekinesis]], etc.  A world's Psi bias level affects the level of common psi skills the world's inhabitants practice as well as the chance of success of psi skills.<ref name="Referee's Rules" />
*''Magic'' (a.k.a. 'mag') covers not just spells, but the supernatural world at large, using the explanation that the ritual of a spell (a spell being anything from a prayer to alchemy) channels expectation of the spell-caster into a desired effect.  Mag skills include summoning spirits, incantations to create fireballs, [[Rainmaking (ritual)|rain dances]], ritualistic curses or blessings, etc.  A world's Mag bias indicates the level of ritualistic magic practiced by inhabitants as well as the presence of supernatural beings and phenomena.<ref name="Referee's Rules" />

The higher score of a particular world bias, the easier related tasks are.  For example, in a universe with a high magic bias and a low technology bias (compared with modern-day Earth), players could expect to see a world similar to [[medieval Europe]], but with wizards and dragons abound.  A moderately high Technology bias, in conjunction with a slightly higher Psionic bias could put the character into a world very similar to the 2002 TV show [[Firefly (TV series)|''Firefly'']].<ref name="Referee's Rules" />
