Oblivion holds dominion over death in all its forms, decay, disease and the restless dead. The forces of Oblivion are allied closely with those of the Dark, with loose ties to Chaos. The forces of Holy and Infernal magic in some ways depend upon Oblivion, and tend to be, at best, uneasy allies. Oblivion is the other half of the Great Cycle, diametrically opposed to the Gaian power of Life.
Aggressive applications of Oblivion are limitless
The best defense is a strong offense, right?
Servitor undead (as opposed to the Willful Undead), spirits of death, decay and disease, and the restless dead by pact
