The Warden and the Rule (Auscheron Book 1) by S.A. Ervin

Kings and queens, lords and ladies, saints, titans, tyrants: by their otherworldly blood the Wardens preserve their home of Nexus from an endless tide of demons.Lorne Auscheron is an heir to that legacy. For nineteen years he has prepared to play his part in the survival of his people; and now, finally, that time has come. Rassala awaits, a world where an army of all-too-human paladins crusades against a brotherhood of beasts over faith, blood-soaked land, water, and scars of history so deep that even the Wardens would respect them. Lorne’s mission there is to dispatch the greatest lord among the beasts…But soon he runs headlong into the ultimate rule of his people: the charms and troubles of other worlds should never become a Warden’s, only the kill matters. And the moment Wardens forget that– the moment they are weak– is when the demons of Nexus will flood forth and doom everybody.The Warden and the Rule is the first book of a four-book fantasy series. All four books are complete and will be released before the end of 2026.
