Help Please

Ok so I've just joined, and I'm not sure where to post first (in terms of roleplay) I looked through a lot of things and there was a spot of the beginning for everyone, but it seems people have moved on form there. So do I still post there, but make it that he's alone since others have move don or do I post elsewhere and mention is reaction to when he had first arrived?

I don't want to make any mistakes so if someone could tell me I would very much appreciate it :3
