I have but only four characters who I truly maintain, though I have had others in the past. They have either all finished their story arcs or have been put on hold for the four primary ones to carry out their interests. Uniquely, in almost no circumstance have any of these characters ever been found in an actual roleplay, as I do not try to wedge characters in, rather I attempt to dynamically develop one for each game I find myself in to best fit the world and its theme.
