Welcome to p99 Kosak.
A great place to get an understanding of Norrath is the
P99 Wiki, which is managed by Loramin. You can even contribute as your knowledge grows by playing the game again. This subforum is good place for new players. Once you decide on Blue or Green you can find discussion in their respective sub forums. Also Discord link for p99 is on the front page if you need quicker replies.
Other server info is typically supposed to be relegated to Off Topic.
Glad to have more Old school EQers around.
