oh yeah mine really spun out of control
so initially the titular character, vainglory, was a D&D character. I gave her a couple fun, energetic traits, but she was not complex. then, gradually, as we went through the first campaign, she became more and more complex and developed a more and more detailed backstory. slowly, she began to interact with the themes of romance, humanist and hedonist philosophy, abuse and self-loathing, and compartmentalization
several years later, I drew her buff and I was like "I need to continue drawing her" and thus the comic was accidentally born
