For over half a dozen years, I've had this goofy little lynx boy named Lukas B. Ice stuck in my head. The Tryne Returner (sometimes spelt Tryn) is a series I've made to put him, and many other OCs into situations. These situations have been strung into seven distinct (but absolutely connected) stories. Unfortunately, I have struggled to adapt any part in a satisfactory manner (though multiple cancelled webcomic runs constituting what I consider to be the fifth part are available).
The Tryne Returner focuses on three main characters: Lukas, of course, a former Colonel in the West American Federation Army (A fictional alliance of countries spanning (in our world) Southern California to Chihuahua), he's also really bad at aging; Doctor Lana Skye (No, I was not aware of the character from Phoenix Wright: Ace Attorney with the same name when she was created), a beautiful white cat with a sharp wit, and a PhD in physics; lastly, Research Fellow Sebastien Urren, a transgender torbie cat who is best friends (and occasionally lovers) with both Lukas and Lana.
