Sigil: Planar Legends (or S:PL) is a Neverwinter Nights persistent world (online server) meant to offer a unique and diverse roleplaying experience in an environment where the players can affect real change in the multiverse. NWN was originally launched with the development tool that Bioware used to create the game itself: The Aurora Engine. Using this engine, teams of players have been able to create new worlds, races, classes, etc. in an effort to forge their own campaign settings. The second tool Bioware gave to the community is the Dungeon Master client. The DM client allows those in charge of a persistent world to act as storytellers and gods alike; to change the world, create and control entities in real time, to do nearly anything that the story might require. Between these two tools, NWN offers a truly amazing ability to facilitate roleplaying in such a way that few other video games or online platforms have since achieved.
The setting of S:PL is an older Dungeons & Dragons campaign setting known as Planescape in which characters stand side by side with the deities, fiends, and still stranger beings held in awe and superstition among other D&D campaign settings. The focal point of S:PL is the city of Sigil, the metropolitan center of the entire cosmological multiverse, and it is believed that from there characters will be able to scheme or consort with all manner of entities as they strive to leave a lasting mark on the planes themselves. No matter your character's goals (from scratching out a planar fortune to even becoming a deity), there is almost nothing outside the realm of the possible when dealing with the Planescape setting.
So whether you're an old hand at the game, or a newbie interested in what NWN and S:PL can offer you, please come and take a look. We'd love to see you.
