I have an idea for a campaign, but I am a new DM and I wanted some thoughts form others. The idea is that a world has been mostly taken over by creatures/monsters, and has reached out to other worlds for help. The only remaining kingdom has offered payment to adventurers to go into the infested area and look for anything of value (magic items, gems, ores, information on enemies, etc.) I have ideas for jobs for the PCs to do, along with a possible reason to why the area is infested, but I would like to know what others think of the idea.
