The 4 dimensions mud reads very much like a history lesson — its text is descriptive out of necessity. In this Wild West mud, users are encouraged to roleplay – and even fight one another. Here is the description when you first enter the Old West mud:

By now “civilization” and science have changed the world considerably. There were horses and carts during the medieval era too of course, but now there are trains driven by steam engines. Robin Hood and his merry men used the longbow, which was a formidable weapon, but the ranged weapons in the Old West are much more powerful firearms, like Winchesters, revolvers and shotguns. And during no time period, before or after, has the horse had such an important role in everyday life as here.

Maddock is a fictional town in the Montana Territory set in the 1870′s. Similarly to Sigil, there has been an attempt to historicize the roleplaying within this virtual world. Their website serves as an incredible resource, documenting the (fictional) history of Maddock, events, and profiles of roleplayers, including Isolde Balcombe.
