Beneath Ceaseless Skies - My Sincere Apologies For the Demon by Adrian Ward

Regarding the banishing of Erimodius, you shall, I expect, be most pleased to hear that he has been returned to the Realm of Flame. With the aid of the Parthiet Warlock Gentlemen’s Circle, additional seals have been placed on the Realm in its entirety until such a time as Erimodius ceases banging on the gate. It may currently be more difficult to summon minor spirits of flame; you may rest assured that such difficulties are temporary.
