Unconventional, you say?
Well, one that got me a lot of raised eyebrows was an elf War Wizard I had, rather arrogant and liked to blow things up, was involved in a bit of a love triangle. His parents were killed by orcs, so he was 'taken in' (This was 3.5, so he was already pushing 80, but 110 was adult for elf), by a family friend who ran a wizard school, a 250 year old elf female wizard. He proceeded to fall in love with her (already had a bit of a childhood crush on her) the more time he spent at the school, so he ran off.
The other part of the triangle was an 'exchange' student at the school, a Drow Sorceress who specialized in enchantment spells who become rather enamored with the Evocation wizard. She proceeded to make it a personal goal to make him her 'servant' or whatever the hell female drow call their mates. It was said that she was mostly turned on by his 'don't give a crap' attitude and ability for massive destruction, but the fact the two actually got along rather well before she got the idea to 'tame' him complicated things.
So, he's running from his teacher, his friend the drow is hunting him, and he just wants to live to blow stuff up in spectacular fashion. Fun times ensued.
