That was nice of you to turn over the title =D
Both titles for my current comic have been used for other things. The current title, Galebound, was in use by a small indie gamedev group but as far as I can tell they seem to be defunct. Also, the domain name was available, soooooo....yoink! I figure gamedev group and comic are far enough apart that even if they were still around it'd probably be fine to share a name. Book and comic, however...yeah, kinda close.
The original title was...not generic, really, but a well-known phrase: Noblesse Oblige. There's a major webcomic called Noblesse, anyway, so that was a mess I didn't wanna get into. Thus, name change! (Noblesse Oblige will work its way back in as a chapter title later).
I've got another comic to do after this one and I will be 100% darned if the main title of that hasn't been used elsewhere, but that's what subtitles are for.
