Mine was in Skyrim. I was an Imperial and Imperial soldier on leave at my house in Solitude. I was wondering the market when Jaree-Ra instructed me on his heist scheme. I agreed and sunk the ship, when I found dead Imperials on board I was pissed, Jaree-Ra's sister tried to kill me on that ship, I killed her and got her note and went to Broken Oar Grotto in full steel Imperial armor, including and Imperial sword and the Imperial Helm from the loading screens. Previously in another Solitude quest I had to clear Broken Oar Grotto for Captain Aldis. When I arrived in the cave everyone was already dead, since I killed them earlier. When I got to the end of the cavern I saw Jaree-Ra crouching down one of his dead comrades and he said "Who did this?" I then jumped down, he turned around saw me, and I one hit decapitated him. I felt so badass when I did that.
