Scry An automagic master server for NWN2 and NWN1.
Thanks to Skywing, NWN2 players can now use Client Extension to view this server list ingame. If you're a server admin and still need to be included, you can either install NWNX and xp_bugfix 1.0.20 or email us at email@example.com. The current player count is in parentheses next to each game.
