1.  Killing innocents while a werewolf.  Dishonoring his family.  The undead get him a touch more disturbed than the average adventurer, but he'll face them down, nonetheless--he's more religious, or more appropriately<em>spiritual</em>, than the average Nord, and so takes the desecration of a being's life-energy as a great blasphemy, and...as he is already cursed, the idea of becoming an undead absolutely makes his shaggy hair stand on end.  He has no qualms about any living creatures, though eating most seafood other than fish or shellfish disgusts him.  He abhors poison, and somewhat fears a death by that, as it is a dishonorable way to die, for him.  He'll choose the glory of death in combat over any other way to die, and is the sort who will go down swinging to the last ounce of blood.  Death holds no fear for him whatsoever, like any good berserker, as he's assured of a nice comfy spot in a mead-hall and daily battles for all eternity if he covers himself in gory glory.<br/><br/>2.  Honor.  This guy is very akin to a pre-Meiji period samurai crossed with a Lakota indian.  He respects nature greatly, and righteous authority.  He isn't above sneaky moves--he isn't the 'tight-ass paladin' sort of honorable--and he'll fight dirty with tactics he considers fair on the battlefield, but he won't resort to dishonoring an oath in any circumstance, ever.  He struggles with his conscience over those he kills when a werewolf, as he has taken the lives of innocents before, but he has rationalized it as part of Hircine's curse--in his human state he'd never do it, so if he kills someone he didn't mean to, he regrets it deeply, but accepts it as part of the vileness of his father's would-be bride asking for the curse to be put on him<em>in utero</em>to begin with.<br/><br/>3.  Aelfgar's a fairly simple guy, though he does love rare foreign dishes and all sorts of booze.  Not surprisingly, he holds his liquor very well, and doesn't often get drunk, but a celebration of a hard-fought victory can see him being the happy drunk every so often, slapping some of his poor compatriots a bit too enthusiastically on the back, or lifting them off of the ground to carry them around on his tottering shoulders until he falls over.  He has a fetish for well-crafted, exotic daggers and knives, and has a collection of twelve or so on his pack horse, but he doesn't use them for combat, and they are not enchanted beyond durability and rust resistance.  Flash a keen new slicey-slicer in his face and he'll pore over it for hours, soaking up every nuance and twist of the hilt, seeking to improve his own craftmanship.<br/><br/>4.  The afore-mentioned undead.  Even simple animated skeletons give him the creeps.  Non-corporeal undead like wraiths, ghosts, spectres, banshees, or whatever Skyrim contains will have his eyes bugging out of his head.  If he ever ran up against some truly powerful baddie like a lich, he might conceivably have a serious affect on his fighting ability, but I think that, with a lich, that goes for everyone involved, anyway.<br/><br/>Hey, don't forget to give us<em>your </em>answers for your<em>own </em>questions!
