@Jarl Coolgruuf You seem to have a good idea of what the RP is like, but just to go through the normal procedures:
I recommend that you read the opening post if you haven't already, and the Summary in the second OOC post. The summary goes up to page 13, so when you finish it you can continue by reading each post's summary from page 14 onward.
We also have a wiki that has some cool stuff that you can check out (link under FAQs).
Once done, you may begin working on a Character Sheet for Pelegath and submit it here. You will generally get some feedback on the initial sheet here from both GMs and other players. Once all that is done, the GMs will retire to consider your character sheet and either accept or reject it.
