[@EchoicChamber]Hey there. I'm not a GM here, but from what I've gathered, I could try and answer some questions.

1. As far as I can tell, your character and backstory can be completely up to you. There seems to be a lot of variety and having a newcomer to the town would probably be a welcome addition to the group :)

2. We already have an accepted character who only has a written description so that's fine. You can always include the picture in a hider as a visual reference rather than the actual portrayal if you so desire

3. This RP seems to be very "craft it together spontaneously" kind of deal. LazerSyrup's post delved into the technological aspects of the world, and in my CS (Damien) you can find a version of the afterlife that I written myself that I thought could be pretty cool for the RP.

[@Letmehaveone2]I'm sure the GM here would be willing to confirm or answer your questions too :)
