Titles are hard. I try to avoid them whenever I can. :P That, and in 1x1 it generally doesn't matter too much. My advice, keep it simple.
If it's fantasy, this may or may not be a formula that works.
'The (character/species/role/conflict) of (setting or important NPC quest giving position)'
Just pick the option that gives the most information in the fewest words, or that might incite people to click because they want to figure out what that word means(<this works for me, might not for anyone else...).
If it's not fantasy... I got nothing.
