Until we can implement a language token system, the only languages your character may know are common, their racial one and then your int bonus of the more common languages. These would include goblin, orc, elven, dwarvish, hin, sylvan (for elves, druids, and rangers only), {celestial, infernal, and abyssal (clerics, paladins, wizards, and blackguards only)}, druidic (druids only), thieves' cant (thieves only), gnoll, giant, and gnome.
