Witcher Warrior Scholar Spy

Decades ago, the four Heroes of Exile returned to Contraria and defeated the Doom—a malevolent, magic-stealing force set on the island nation’s destruction. Now, the Doom has returned hundreds of years ahead of schedule. The next generation of Heroes are far from home and spread across the continent when they feel the Doom return. Tasked with rebuilding an ancient artifact and fighting off the evil that was consuming their homeland, they must find each other. They didn’t expect that would be their first struggle. — Description from novelcodex.org
