My characters like punching stuff. I like punching stuff too.

The closest character to myself was probably this swordcaster mage, descendant of a gypsy clan. Always brooding, stoic to the death; due to his pessimistic view of the world and a severely lacking inner drive, he overall remained a complete amateur in his area of specialty, his spell arsenal consisting of a single complex and incredibly nasty conjuration on the backdrop of a slew of weak and low-effort tricks. Obsessive care and maintenance for his tools of trade and a complete disregard for everything else material in his life - clothing, appearances, household and personal health.

So basically he was a hikkimori barely keeping his head above the water thanks to being lukewarm successful in his only field of self-realization. Pretty apt description of what i was like at the time of writing the character - what makes it funny to me is that none of the similarities were intentional and it's only in retrospect that i saw them, way, way later.
