Dark Archer is who he is. I'm not trying to be cool or whatever. He's just a resident of a bad end type thing. I prefer my sheets to be simple. Five page back stories are irregular.
No/almost no backstory is irregular, not the other way around.
You do not prefer your sheets to be simple, you prefer them to be effortless to make.
And calling him "Knight of Chaos" is definitely trying to be cool and edgy, along with the trench coat and other assorted faggotry.
