The Uncharted Midlands: Last Gate is a NWN1 persistent world with a focus on social heavy role playing, low-magic and low-levels. One of the features is also permadeath, which means that once a character dies, it cannot come back to life in any way.
In the server players can build their own structures by gathering stone and lumber, and then requesting what they want to be built. The structures are permanent.
The server uses original, players-contributed mythology.
