To save his realm from a plague, he must make a deal with a devil. After dealing the devil army blow after blow, Primal Conjurer Ryn Xaven learns they have one last weapon in a plague they will release if they lose the war. If the devils can’t invade Ryn’s realm, they’ll simply slaughter everyone in it. Only one narrow route to victory remains. Ryn must convince the devil that possessed a noble valkyrie to help him find and destroy this plague. The only problem? She just escaped into the wilds. With the help of his loyal auxiliaries, Ryn must track down the possessed valkyrie and save her soul before the devil inside her can consume it... and his last chance of saving his realm.
