Honestly I hope this doesn't set a precedent. Why? Because it'll be too damn confusing! "Who's that, I've never heard of him?" "Oh, well that's the guy who used to be Chivalrous, but now he's called Ascelon." "Oh, what about that guy?" "Remember so-and-so? Well he changed his name to..."
Pain. In The. Ass.
Now, if it's just Chiv, I'm ok with it, cause I can remember one. But beyond that, how the hell am I supposed to remember who's who?
That said, if you've been trying for years to not be an adjective and you've finally succeeded, congratulations.
