One of the first characters I've made: A Dragonborn, with a tail because I felt it was needed. I also wanted that tail to have a flaming tip. No, I totally didn't copy that from the Charmander line.
Then I worked my way out from there. What sort of character would he be?

Eventually, I ended up with a Fighter 1/Cleric 2 of the Death Domain. And he's been fun to play thus far.
And no, he's not Evil. He likes to think of himself as a guide to the After, and his god's mercy. Death claims us all, and if it is your destined time? He will guide you. By force if you insist on clinging to (un)life.
