[member="Atheus"] - It sounds like you're basing your argument off of false information, and the belief that being a Knight of Ren inherently ties you to the First Order. While our Lore, something our Faction strives to pride itself on, respecting both the Star Wars canon and that of which we make ourselves here on Chaos, would state that to be a Knight of Ren - you'd have to be a part of the Faction. With how open ended the current Lore is, and the many possibilities this site and it's timeline allows for - it's more than possible that the Knights had a schism of their own sometime in the past, much like the Jedi did, which causes another sect to arise elsewhere in the Galaxy. That's the beauty of Chaos, the ability to mesh both Legends canon, and the true canon timelines - then sprinkle a bit of salt bay flavouring of our own. So, while it may be entirely possible for what I've said to be true, it'll add some interesting dynamic(s) to our stories if another sect arose, as it could lead down the road of one sect fighting the other to curry their Master's favour.
Being labelled as a Jedi, Sith iherently ties the Knights to faction's in canon Lore, that they've already exterminated, or fundamentally replaced. So those tags would really capture the essence of what it means to be a Knight of Ren. The Neutral tags wouldn't really work either, as the Knights are a primarily Darkside sect - minus an aberration here or there that's being done as an experiment. That's like telling Revan he's not a Jedi, despite the canon lore had him redeem himself after the events of KOTOR. At least in my opinion. The Dark Jedi tags are close, but far from appropriate. The ideals of a Dark Jedi are to serve oneself, and their own desires. The Knights of Ren are on the opposite side of that ideological spectrum - built upon mystery and brotherhood, the strong are strongest together, and so on and so forth.
So, I can understand why those who don't write with us would say, just use what you have and like it, but as I briefly touched on above, it doesn't really fit who we are. I can also understand [member="Tefka"] 's point of waiting - I don't like it, but will swallow my pride and bide my time. The tag won't affect our stories, or our Faction's Lore, but what it would do is be the icing on our RolePlay Cake.
Apologies for the rambling - it's early in the morning and the urge to type on my phone was strong.
