What is the name of this game?

There was an online multiplayer game I used to play sometime between 1999 and 2002. It was a VERY simple game. I remember there was a map. I think some people would create maps on servers. I remember and you could battle creatures or other players. I think you would use “magic spells” among other things to battle. You could also create groups or clans with other players and go on quests. I think you could change skins and they were very simple. It was a really addictive game. Many people played it but I don’t think a lot of people remember playing it. It probably doesn’t exist anymore but I want to know the name of it just to see pictures of it and see what happened to it.
