Got medieval on them

this continent has the biggest, evilest monsters from every story. And I do mean EVERY story, from bed time stories, to myths, to legends, to videogames, basically if it was a story or something that was created out of imagination it was made real to an extent. All of them were made real. When the explosion hit multiple class nightmare threats came from the sky and completely annihilated the people living there. But what the nightmares did not expect was a society ready and defended for their arrival. the shields were down and the turrets were blown up. But the people came together and created the dead god initiative. At first it was several skilled mineters who fought off the first wave in 0 a.e. after that they were disbanded due to a morally crushing victory in 500 a.e. with over 700 members, but several still remain. They became traveling heroes, going from town to town fighting monsters, dispelling demons, negotiating land, beating game spheres and helping out whenever they can.
