A multi user dungeon is a shared world you read and type your way through. You make a character, choose a people and a class, and walk out into a land where - as the old intro warns -
“all races aren't good friends here and you must very carefully take care yourself.”
"Stonia is like a synonym of Ancient and Mythological Estonia," as its founder RalfII put it. Lindanise, Dorpat, Oesel and Lake Peipus sit on the same chart as Moria, Barad-dur and the Shire.
Stonia keeps its old pace and arithmetic: a combat round every 2 seconds, experience counted as in Stonia (a hero sits at 282 million exp), and heroes from level 51 climbing on with warpoints. Player killing is allowed between different skins.
