Well hello again, I put the wiki onto your introduction. If you follow some of the links on the front page it gives you a general idea of where to start in terms of figuring out the lore and such.

As for the character application, I can give you a link to that page.

The top of this page has a few links to help navigate things a bit. All you really need to look at are the Character Application Rules, Character Application Template, and the Character Application Example. You can also go past that and look at some of the character applications other players have made. The ones with the Approved Tag would be the best to look into since those have what we are looking for.

Before fully diving into an application it is always recommended to role play a bit in game to get a feel for the character you are making. Once you have a general idea of who they are you can make a quick little sheet for their proficiencies (I usually use a piece of paper at my desk or a Google Doc to just quick get it written down.)

Hope that this helps you get started off. Any questions, feel free to ask.
