Has kaos retired from writing comics?
Yes.
Normally creators just disappear, but in this case Stormbringer, whose stories Kaos illustrated, stated she left the biz because she couldn't successfully monetize.
Of course, she went with the old shitty paysite model, where you need to entrust your credit card info to some skeezy offshore outfit, rather than to set up a patreon, so...
Anyway; one of the very last things she did was to write an episode of Blacked (the real-life xxx video series), where Naomi Swann visits the HQ of Blacked Inc (released Sep 12 2019).
