Abandoned Codex is a modified Smaug/Diku MUD with optional (encouraged) roleplaying and optional pkilling. It has been running and developing since 1997.
Set on the fantasy otherworld of Arathnos, its main focus is the once-proud but now crumbling city-state of Xantheus. Her government collapsed, the city is run by an uneasy balance of the military and the clans. Far to the west, the tropical island of Pentir beckons with easy riches and new dangers. To the south lurks the stricken continent of Djakiar, with its magical storms, endless desert, and absolute rule of law.
And finally, the Codex itself. An ancient pact made between the Gods and the Mortals, whereby the Gods gained power from their worshippers, and in turn fed that power back - until greed destroyed all but the last fragment, and the Gods left the world. Many have searched for signs of their return; will such an event prove welcome?
