For the experienced LPMUDder, Viking looks very much like old Genesis, the first LPMUD. We have not changed the layout of the backbone area, mostly for nostalgic reasons. However, other things are very different from the 2.4.5 mudlib we started evolving from in February 1991, such as the various areas that have been added.
VikingMUD is a rather social MUD. Communicating with other players (the commands tell, shout and chat) cost no spell points.
Playerkilling is allowed under very special circumstances, such as areas designe with that in mind, but in general, you may not attack other players. (See the rules.)
There are several so-called guilds on VikingMUD.
In addition to the guilds, there are two clubs for the players to join. The Bastard Batallion and The Eagle Club
