Yes, it is open to anyone, so long as they join within the first four to five days. I want at least three to participate in this trial run. Once, I have at least three confirmed and on opinion on the idea below, I'll start the story.
(Remember, this particular STS is going to have a requirement to post in the TS at least once a week, if you wish to participate in both. You can replace one of your STS posts with a TS post once per week.)
I think that I shall explain my idea now. If people don't like, we'll try something else.
First of all please read
this topic. It sets up the setting that I have in mind.
The STS would take place hundreds of eternities (in Cythera time) before Cythera was formed (I don't think anyone but myself and a few others-none that I know of in this topic-has a character that old, so it'd require making a new character just to test it). It would tell the story of part of the war between the Chimaera and the Death King. Characters could be servants of one side or the other, those mentioned that fight in the war but don't know it, people who work for neither side, and even some members of the Chimaera.
This only a suggestion.
