A local noble has sent two previous expeditions to the Ragnarok Tunnels to hunt down a thief who stole his valuable visionary orb. They failed! Your group, armed with a magical orckilling sword and plenty of healing salves, makes their way to the entrance only to see a horde of orcs guarding the way. This is just one of many obstacles your valiant group of adventurers will face in these dangerous Ragnarok Tunnels. As you encounter the many personalities within, will you ally with them, kill them or find yourself trusting no one and fighting alone?
