I think that C.L.O.A.K can have the best chance of entering in,
Mostly because the Aetherlight hasn’t gone into terms with the history enough to actually have any rules around it. As in the timeline is really what matters. The other roleplays consist of factors within certain characters and storylines that go against the rules making them unable to fit within the universe of the Aetherlight. They are Legends.
I try to make my roleplay entries as canon as possible unless writing for a roleplay out of order from the Aetherlight. (Like skyradiers of course.)
But any roleplay that doesn’t have any major things against the canon Aetherlight can still have a chance because there’s always a way to fit together pieces. For instance: let’s say a character has a situation with Lukas (the Aetherlight character) that includes experimentation with explosives in a time before he started experimenting according to the Aetherlight timeline. A way to solve this could be using the fog to make him forget, and so the whole situation could’ve happened without messing any rules up.
That’s why I’ve always thought of this roleplay, it fits perfectly within the canon and is a whole different level of story telling.
There are a few other things I have in mind, they are probably just as big or even bigger, but let’s just start here.
*Canon is any real things that are accepted and included into the actual story of whatever; official. I know the canon for both Star Wars and marvel,
While legends is the opposite; non official, so any ideas not included in the actual story, but can be widely popular.
Legends can be converted into canon, for example the character Thrawn. Timothy Zahn created the character at first as legends, but Star Wars decided to included so now he’s a character!
