(Morgengrauen is the german word for 'nightfall')
I want to advertise for a text based multiplayer game, that exists for far over 20 years. We still develop new quests, locations, enemies, races, guilds and more. You usually login with a telnet client or a specialized mud client, but you can also use the web interface on the mud website. You find it here: mg.mud.de
I recommend to use putty
as basic telnet client, a program that is able to connect via ssh.
