That's a fantasy mod I'm working on since on year, with models from other mods, and working on the .txt files of the game (not with the module_system). I don't upload it for the moment because I have to shorten it before (it is too big to be uploaded). But if you insist, I may did it soon.. ;) This mod take place in a fantasy world inspired by the universes of Lord Of The Ring, Warcraft III & Warhammer. There are 6 factions : Humans, Orcs, Dwarven, Goblins, Elvens & Dark Elvens. It does not add anything for the original game (except that Nirecotive is available for the multiplayer), and it's really did just for play Mount&Blade in a fantasy world instead of the realistic world proposed by the Native version. But, it also change a little the gameplay, because you'll not have to fight only humans, you'll have to fight against (or to be, as you want) monsters that are very weak or very strong, and you'll have to make a real choice for your character class, influencing your gameplay.

Inspired from, yes. But not really. :)
