The timeline uses ABY (After the Battle of Yavin) when the 1st Death Star was destroyed, a major turnig point in the franchise, so 849ABY is 849 years after the Battle of Yavin.
People RP here as resurrected versions of famous film factions like the Mandalorians, Jedi, Sith, First Order...whatever reall. We don't RP as ANY official canon chracters like Luke Skywalker or Kylo Ren as we aren't here to write the furure of Star Wars, we just play in the expansive playground with our made up characters using their planets and factions.
It can seem daunting at first, but when you get into it, it's not too bad. Let your imagination soar and have fun with creating a character - they can be evil, good or in the middle. Or even neutral, like a bar-tender or transport pilot. There is no "YOU MUST MAKE THIS CHARACTER" rule to enjoy writing, so just go where you creativity tells you.
Please keep the questions coming so we can help you get started.
