Antikaria is a MUD--a multi-player, text-based adventure game. It is still being developed and is not yet open to players. The mud server is written in C# and is running on Mono.
You can connect to the mud by connecting with a mud client or telnet to antikaria.com port 9000. Since it is in constant development it might not be available all the time. If you can't connect, try again later. See the Connect page for more information.
