Shadows of Amadeus

Two thousand years ago, a monster known only as The Beast ravaged the world, spreading war and destruction throughout the multiverse. Millions fought and died, but it seemed hopeless, until finally a group of heroes defeated The Beast in a fearsome battle, trapping him in the three artefacts that summoned him. But now someone seeks to resurrect The Beast and finish what began millennia ago: the end of the world. Now, only a handful of survivors remain to combat those who would resurrect The Beast, but how can they fight an enemy that they cannot even see?
