I'd add Karmagik and Jimmy to that list. Amazing artistic abilities to the side, Dtiberius is an oversensitive, egotistical nut-case
You're right on that mark. He has a list of comics that were never finished.
True and he hasn't given an update in over a year.
Unfortunately, that's not an effect of his character. He's been suffering (and unknown if recovering) from a serious illness for the past three years. This, combined with being underemployed and having less-than-mediocre health insurance, has all but halted his perverse hobby.
I don't think it's of any overstatement to say, the only artist on WWOEC who has ever been successful at supplementing their living with their work is PBX. And that's only because she's made such a prosperous partnership with Milftoon off the coast of Africa.
Still, I'm praying for D's health and return.
