Completely back on topic. I have a feeling that I'm on track here, but I may be just heading off into a field to become a jumble of boxcars. If so, slap me back in the right general direction please.

With this character, use each of the four numbered techniques above (summary, habit, self-portrait, physical) to introduce your character.
After much flailing, I have seized on the word 'introduce'. In introducing the character I may or may not include everything I have in his backstory. In fact, upon further flailing, I probably won't.

My purpose is to present the character in a way that doesn't conflict with the backstory, since that will eventually come out. Also, most importantly, in a way that engages a reader in the character. Probably not jumping directly into the character's conflicts before getting the reader engaged, so leave them out when introducing the character. Hmmmm. My feeling that I was on track is fading fast, but I might be getting on track now.

Sorry for blatantly brainstorming all over the place here, but I really needed that! Again, if I am completely off track please say so...
