In Oblivion I was a poltergeist and a twat, boldly walking up to people and punching them in the face, but because of my 100% chameleon stealth armour, they though I was either the wind, 'damn rats', or the effects of too much beer.
I'm sure my exploits have caused an urban legend in Tamriel, about how, on windy nights, when you've had a little too much to drink, invisible rats will shoot you full of arrows, set you on fire and steal your pants.
