Itropa is a Persistent World for Neverwinter Nights. It takes place in a completely original universe, with an eclectic level of technology. It uses no hakpacks, other than the CEP. It is a world that has no gods or magic, but this only affects the roleplay, not the gameplay. All "magic spells" in the game are scientifically explainable. Players are allowed to come up their own explanations for their "magic" abilities, for example, psychic powers, genetic manipulation, radioactive mutation, alien heritage, cybernetic implants, embedded weaponry, nanotechnology, and so on.
It is a roleplay server, but the rules are kept light, and the mod doesn't take itself too seriously. If you wish to know more about the rules, the world, and the characters within it, please visit the message board.
