I was just checking to see if there are any out there. I've had the system for years and have never done anything with it. Was reading Solo Leveling and thought it was an interesting idea for a campaign. The characters are entering gates that have appeared in the world trying to close them before a dungeon break occurs and the monsters in it are released into the world. Meanwhile they can get hints on why the gates have appeared and try to find a way to close them for good.
