True Name of Yog

Description
"Some gods are strong to harm, others, to aid; at least so say their priests."

- Queen of the Black Coast

Learning true names is a study that sorcerers use to contact the demons of the Outer Void. Such sorcerers have volumes full of the names of their familiars and allies.

The true name of a god, however, burns brightly in the mind when spoken, then flares and fades into nothingness. Once spoken, such a name is forgotten immediately.

This name then, carved in stone, is a priceless gift. For a short period, the gaze of a god will be upon the speaker and they will be lifted to heights of power undreamed of. But men were not built to live as gods, so the power is fleeting.
