There are mods you can download and install that I've seen will add extra mobs/characters in the game. I think I remember seeing one that added human NPC's, but I could be remembering wrong. A quick Google search will help you find mods. Just remember that mods are *not* supported by Iron Gate, but they don't discourage the use of mods either. But you do run the risk of messing up your game and you'll have to then trouble-shoot it yourself (although the modding communities can be very helpful sometimes).
