I rebooted my old series because I hadn't updated it in something like 10 years, I felt like I'd painted myself into a corner due to back in the day never really having planned out my stories (because I hadn't spent time learning things like story structure) and in the meantime I'd realised I was gay, so all the coy jokes and homoerotic tension felt silly after actually coming to terms with my sexuality and realising I'd actually just like to make characters gay and be relaxed and open about it. In spite of all that, I still loved the characters in personality and design, and I knew I had a few followers with fond memories of the comic, so rather than coming up with something from scratch, I heavily reworked it. Different plot, some changes to the setting, but it keeps some of the lore, the basic premise of "group of dysfunctional magic knights fighting an unjust political system" and things like the sword draw attacks with runes and the protagonist's key skill being super-strength.
Obviously after ten years spent as a professional illustrator in between, the art is waaay more polished in the new version.
So, old version, Fan Dan Go:
