This might be a bit more complicated, because the comic I'm looking for is not well known, I think it was 4-5 issues, might have been from the late 80s, mid-90s, not sure about the publisher. Probably independent. I read it once a years ago but can't remember the name and my googling isn't turning anything up either.
- The setting is feudal space opera. It reminded me strongly of the "Fading Suns" universe, a d20 roleplaying system.
- The main protagonist is a monk/priest-like character who is called to a planet to root out corruption (which he does very efficiently).
- Small detail I remember: Protagonist roughing up a pimp-like character, surprising him with his pendant that essentially is just the pommel-weight of a concealed kusari-gama-style weapon (weird detail to remember, I know).
- The comic's artistic style places it in the vicinity of 2000AD, Heavy Metal magazine, particularly Simon Bisley or Glenn Fabry.
