Picture this:
You're a Winterhold guard. Winterhold, which is barely a hamlet anymore, its former glory washed away by The Great Collapse, the only hints of that glory being the ruined state of its walls, while most of the few buildings still left standing are boarded shut as their owners left for Dawnstar or Windhelm. It pains you, as it would pain any Nord, to know that now the only thing keeping the city you were born and raised in from being taken by the snow is the thrice-damned College.
And it's salt in the wound, really, to know that it's the wizards' fault. They claim it's not, they say it was a volcano, or it's a mystery. Even though the only structure left completely intact was the College itself. How convenient.
You're a Winterhold guard, wondering if you did the right thing by staying, wondering if you should have gone south with your ex-fiancé before he gave up on you in disgust and left, guarding the gates that no one's assaulted in years, when you see a lone mage walking down the beaten path towards the city. And he's certainly a mage, you know this even before he's close enough for you to see the shimmer of a spell on his skin, because only mages would be walking in the nude in the snow like that, not needing even enchanted clothes and armour to shrug off the cold.
But as he gets closer more and more things seem strange about him. One, he's carrying a book and a dagger in his hand, rather than in a bag or hidden away in a mage's magical storage; two, he's a human but not an ethnicity you've ever seen before, his shoulder-length hair a silky wave of pure black and his skin tinted bronze where it's not gleaming with magicka or blue from the cold; three, he's blue from the cold, his spell clearly not enough to ward off the temperature, so even if you were right that he was a mage it turns out that the nudity may not have anything to do with that.
"Halt!" you cry once he's close enough, because this is really fishy. "State your business!"
But he ignores you. In fact, you're pretty sure he didn't even hear you. His eyes have a glazed over, frozen look to them, staring directly at the entrance to the city. His steps are stiff and stilted. His grip on the book and the dagger is deadly tight, you'd more easily cut off his hand than take his possessions from him.
And none of that is reassuring. You're reminded of stories of mages going insane you've heard from your dad and friends at the tavern, of them doing too much magic and losing some part of themselves in the process, slaughtering villages for necromantic experiments, making contracts with Daedra, devils and worse. Of the times growing up when you saw or heard or heard tell of mages right here in Winterhold going crazy, the spectacular lights in the night sky above the College followed by silence. If you ask the mages themselves—they are as avid patrons of The Frozen Hearth as anyone, especially the handful of Nords who have not shaken off their cultural heritage and still enjoy a flagon of mead in the evening—they say that it was nothing, just someone being a bit too excited with their research.
Honestly, thinking about it all like this, you think you probably should have left this land forsaken by the Nine.
So it is with that in mind that you prepare for a fight, maybe a hopeless one that'll barely delay the inevitable, because you're still of Winterhold and you'd rather die than live knowing you didn't even try to protect your home.
This is of course all moot when the man promptly passes out on you as soon as he gets close enough.
