Maybe mine isn't so epic but...

1) On my assasin type of character, I was walking down the steps of Dragonsreach and saw Idolaf Battle-Born walking up the steps. I seriously don't like
this character or any of the battle-borns. (except Alfhild Battle-Born ) When we met in the middle of the stairs on the center square I pulled out my newely enchanted/smithed daedric dagger named "Alduin's Fang" and cinematically jabbed him in the gut and walked away. There were no guards or other npcs around at that moment. I ended up walking to one of the benches and sitting down all assasin-like.

Not epic to some but that moment was like a little slice of Assasin's creed in Skyrim.

2) Was clearing out an orc stronghold of those vile creatures and on one of the last orcs I pulled out my "Alduin's Fang" and the orc said "Today is a good day to die" as I cinematically jabbed her in the gut. (Different finishing animation)

I was at Sky Haven Temple last night around 11:30. I was just chatting with Esbern, who had been practicing swordplay on a dummy in the courtyard to keep his age away
Out of nowhere I hear a crash behind me, and turn around to find that a Frost Dragon had just landed in the courtyard 5 feet behind me. I thought it was a pretty suicidal dragon, landing in the middle of the fortress of the Blades AKA the world's best dragon hunters, and the Dovakiin, THE best dragon hunter. It was quite the fight

Needless to say, besides being a ridiculously hilarious fight, the music made fighting alongside Esbern and Delphine pretty freaking cool

i walked across the bridge into the college of winterhold

the end

Found an outdoor bandit camp with two dudes guarding a hefty stash and a horse. Killed two dudes with ease, loot their goodies....and realize apparently six other bandits had been out on an errand and had sidled up while I was picking the lock on their chest.

Super OH SHI--- moment in my character's young career. With much kiting, swearing and potion guzzling I was able to pull it off and ride off on their horse.

Was doing a Dark Brotherhood mission in Dawnstar.

Without the zoom Perk for Archery I shot my target, in the middle of broad daylight, while she stood amongst three people and a guard, from five houses away.

In the head.

Not a single person ever had the smallest inkling it was me when I came strolling up to loot her body.

I was fighting an Elder Dragon on my Bosmer Barbarian. The bastard did NOT want to land, and had been making me hide like a pansy after he knocked half my health down by strafing the area. I fired an arrow, and hit him. It pissed him off, and he landed about 30 yards away. I switched to my sword and shield, just as the barbarian chorus began to chant.

'Dovahkiin, Dovahkiin', as I charged through the dragons fire, leaping forward with my blade. 'Naal ok zin, los vahriin' as I performed the first slash, stopping his breath. I blocked his bites, and slashed his face, each verse, each percussive beat, and each of the dragon's howls making my attacks more pronounced. As the chorus reached it's climix, my character pounced onto the dragon's neck, and the timing was impeccable. With each roar from the barbarian chorus, the Dovahkiin struck the beast's face brutally with his sword. With each shout the chorus spoke, the dragon howled in agony.

When the deed was down, and my character jumped from the dragons head, the chorus died down as I devoured the dragon's soul, and stalked away with my sword in it's sheath.

For you.

Hiding in the tower while the Whiterun guards slayed the dragon, then coming out and absorbing its soul, instantly becoming a hero, and demanding a reward for my brave deed.

Later, I Shouted at a courier in town and Lydia draws her sword and chases the guy off-screen as a guard steps up to tell me the Shouting is making people nervous. But it's not me they have to worry about, it's my insane housecarl.
