[member="Jerel"] Welcome to Chaos first of, I hope you have a great time here
Now as to the RP, a large part comes down to teh kind of story you want to tell. Do you want to be a Jedi, a Sith, do you want a story of war, or one of helping people. Once you have the idea there that you're after then it'll help you figure out what story you want to tell.
Like Jubei said, discord is great, the main Chaos RP has a channel for new players where people are always willing to help you out, and I would suggest joining up with a Major faction on your first character. The Major Factions have a lot more activity going on, and they have the numbers to help you out and guide you through. I joined a few months ago and for the first few days I was lost but my faction, The Silver Jedi Order, was great at helping me out, answering my questions and guiding me along till I found my feet. Of course, a faction isn't required, and there are many people who just play their stories without ever joining a faction.
The way this works is you can either join a public/open RP or set up a private one. Most RP have some kinda progression or story but there are many times people just show up in a thread and write whatever comes to mind, some of the best stories form organically that way. In the end the RP is about telling your character's story, and you're the only one who can tell they kind of story you want that to be. If you're brand new to RP then finding some kind of apprentice role at first is often useful cause it means you always have a partner willing to write with you, and someone who can help ease you into events and the like. THe grand storylines of Chaos exist around events. You have faction events, like a party held by a faction as a way to socialise. A Dominion, where a faction trying to take control of a map hex, an invasion, where you try to take a hex from someone else, or a story thread, where someone creates a story and people just join up to write their characters into it.
Jubei covered pretty much everything else,, browse around the RPs so you can have an idea of what's going on, but don't feel you have to write as much as some people. I've had fun RPs that were just sentence posts, and greats one that were huge long posts, you do what's fun for you.
And if you have any questions, feel free to ask them here, in discord or if you want PM me and I'll be happy to help out.
Again welcome to Chaos, enjoy your time here.
