In the chaotic realms beyond Kadath there are ten Lords, less than gods but greater than flesh, they are Demons of the greater order. Only seven of the ten are known from fragmentary codex known as the Demonology of Ysra. They are to be evoked with the utmost caution for they delight in atrocity.
Auth-Neb knows all the formulae of the gates of dimension and the shapes of time, with proper sacrifice he may give a Magus aid in this work. But if he is called often he will become familiar to the Magus and may take him when the barriers are thin or the seals made improper. The fate of those taken by Auth-Neb is not known, even to the Prophets of Pnom.
