Stormcaller
10,000 years have passed since Asebor was sealed during the first Age of Dawn. The power binding this malevolent god has finally waned, allowing him to once again beat the drums of war.
Men worship the Phoenix and Dragon gods. Some are fortunate enough to touch their essences, transforming ordinary women into fearsome warriors and men into miraculous healers.
The beginnings of the next scourge brushes the town of Breden, where Walter, son of elixir bean farmers, itches for adventure only to discover the harsh brutality of combat.

The Lord of Death
Walter survived his first confrontation with the demon god Asebor when his cursed armor was removed, swelling his thirst for vengeance. It was supposed to be impossible to remain human for long when wearing Cerumal armor.
The shadow of Asebor darkens over the realm of Zoria. Juzo, his best friend, is still missing and has been forced down a dark path. Walter and Nyset harness their newfound abilities under the tutelage of Baylan of the Silver Tower and the rogue wizard, Malek.
The group is thrown into an insidious trap as Asebor’s generals, The Wretched, strike at the heart of Midgaard, derailing them from searching for Juzo. Walter is sure that Juzo is alive and he can’t allow himself to give up on his friend, despite the risks of travelling east where hordes of Death Spawn are rumored to be. The Midgaard Falcon army is deployed to stomp out the Death Spawn, led by a mysterious horror known as the Lord of Death.
