Here is Trahel, a death mage from Rogue Genius Games. I gave up on the hellion/malefactor as the concept of hellknight/tiefling/anti-hero seemed to fill the early submissions. Oddly, picking an arcane 3pp class was also rather challenging, as most don't differentiate themselves well at low levels or suffer from the lack of combat actions/too few spells (White Necromancer, Magister...).
