In a land where Gryphons soar and Spirits walk, Kaiser Adonis is the name of unspoken fear that grips the hearts of all. With a tongue as sharp as a sword and a soul as black as night, he has the power to bring forth the darkest of nightmares. His reach stretches across a thousand years, orchestrating his rise to greatness with rivers of blood. The world is quickly spiraling towards an echo of the tumultuous past, noble war heroes long gone. Cries for help go unheard. Danger lurks around every corner as Kaiser tightens his hold over the crumbling Shadowborn throne. No one is safe. All that stands in Kaiser's way are two sons of the ancient Silvanus bloodline: the royal heir Onyx Silvanus and the bastard rebel Ryder Coba. They are the last hope to rescue their ancestral throne and bring courage back to a world preparing for war.
