Tolfdir killed my fucking dog. What is the best way to get revenge?

So I start a new character who is going to primarily use magic and I say to myself “You know what? I am going to start by doing the College of Winterhold quest line first before anything else.” After Helgen, I run over to Whiterun, grab some spells from Farengar, and start making the trek all the way up to Winterhold.

As I’m going around Windhelm, I come across a stray dog fighting some wolves. Naturally, I help the pup take them down and make a new friend! This adds another layer to what was going to be a pretty standard mage character. I start getting excited for the possibilities of wandering the frozen tundra with my canine companion. Maybe this character will have a more Druidic flair and the thought of eventually taking down Alduin with my trusty dog by my side filled me with joy.

Anyway, I eventually make it to Winterhold, gain admittance to the College, and make my way inside for the first lessons. And that’s when I first saw fuckface and his accomplices. Tolfdir and the students were all friendly enough at first, not giving off any bad vibes that show what monsters they truly were (although Tolfdir kept gaslighting me, saying that I need to “keep the ward spell up” when everyone and their gods could see me holding up the shiny blue bastard spell, but I digress). I’m told to go to the Saarthal expedition, so after a good night’s rest, I begin to travel over there.

It all happened so fast. Almost as soon as the words “Saarthal discovered” hit my screen, I heard someone cry out “What was that?”, followed by the sound of about 5 oakflesh spells going off. I assume at first that perhaps an ice wolf or bear or something made its way down towards the entrance of the tomb. Then I saw what they were all aggro-ing. They were ganging up to attack my stray dog. Before I could help my pooch get out of there, Tolfdir summons a flame atronach that hurls a fireball at him, sending him flying across the snowscape, dead on impact.

I talk to Tolfdir and all of the students, wanting desperately for someone to fess up as to why this horrible crime had just been committed, but not a single fucking one of them even acknowledged that anything happened. I ran away in distress. My teacher killed the first friend I ever made. I was left alone and confused, but I swore that I would make that old bastard and that entire college pay one day.

So that’s where I’m at. A magic college dropout with a thirst for revenge and a heavy heart mourning the loss of his dog. How should I go about exacting my revenge against the institution that can get away with murder?

TL;DR Old dude killed my dog while a bunch of other people watched and I want to make them all pay.
