Thereamid is designed so that you can contribute your own ideas and stories to the Setting. We have a Genre Guide that talks about the kind of stories we are trying to tell, a forum where you can talk in and out of character, and an entire wiki about the world. You are encouraged to contribute your own additions to the wiki, and to create your own characters and stories.
Register and start adding your own ideas to Thereamid!
