In its original, and some would say most compelling form, magic was primarily the art of memory. It required no technology, no wands, or paraphernalia other than the mind of the magician. All the trappings of sacrament were merely mnemonic devices, meant to allow the practitioner to recollect in rich detail the precise mental formulae that unlocked a spell’s influence. The supreme mages in those days were the ones consecrated with the greatest memories, and yet so complex were the invocations that all wizards were forced to specialize. The most dedicated might hope in a lifetime to have sufficient recollection of three spells–four at most. Ordinary wizards were content to know two, and it was common for a village mage to know only one–with even that requiring him to seek advice from grimoires as an aid against poor memory on the rare occasions when he is called to use it. However, among these early practitioners, one genius of vast intellect and prodigious memory came to be known as Invoker.
