Tome, Summoning Grimoire

Few mages can resist the opportunity to add to their font of knowledge. Indeed, the search for the True Names and the ability to summon and command the forces of the cosmos loom as lofty goals for the pursuit of many mages. Respected scholars of magickal theory as well as practicing mages of all levels dedicate their lives to this aim.

Description: A summoning grimoire may take any form; from a genuine codex similar to the ones found in Mayan and Aztec ruins, to a medieval-style libram complete with illumined text that a monk has lavished many hours on its elegantly detailed script and illustrations.

Abilities:

Other lore books and ancient tomes state a grave warning to ambitious sorcerers: the Great Ones cannot be bound by symbol or rite, True Name or sacrifice. No human sorcerer can command them, no matter the power he uses.

Indeed, Great Ones are not only aware of these misconceptions, but actively propagate them. Throughout the world's history, in secret places, the Great Ones set pen to paper, scribing out books of lore filled with supposed magical diagrams and descriptions of rituals that claim to be able to summon and bind a Great One to one's service. It should be clear now, the would-be summoner is using incantations and rituals of the Great One's own making, they will be using mock defenses and summoning that have been given to them, and in truth, no human sorcerer can control them, no matter the power he uses. They cannot be summoned or controlled by sorcery, they can only be “paged”, but they are under no compulsion to show up. Still, many do, if only to explain to the mage that they don’t approve of being summoned. Just like the mistakes that clergy make, summoned Great Ones may feign defeat, submission and utter obedience, even for a thousand years if it serves their purpose in order to give humans a false sense of power over them...so that at the right time for their purposes they can turn and smile at the foolishness of mortals.
