Within the tunnels of a mine in Mor Khazgur, Sariel enters into the realm of Apocrypha, the realm of Oblivion connected with Hermaeus Mora, Lord of Secrets. She explores his library and eventually makes a deal, surrendering some knowledge she has gained, in order to gain some knowledge in Apocrypha. Within the walls of Hermaeus Mora's library, she finds a long-forgotten relic; The Tome of Magnus. It holds more blank pages than filled ones, but it still possesses some knowledge she can use. And given time, something else might become unlocked...
