I need a person who volunteers to take something similar to paladin's role in my campaign. the character's name is Sir Denis

I will provide a general back ground, and you are allowed to do some modifiers as I see fit

the current situation is, Sir Denis is diving into a romance, which I, as a DM feel obligated to play along. (not that I cannot do it, but it'd be more interesting to see my twist played out on other people, instead of being involved myself...)

minor changes are allowed, all roleplayers who enjoy paladins are welcome

NOTE: the character is NOT a actual paladin, he is just lawful good fighter
