(relatively new Oblivion player, 40 hours)

As I was riding my unicorn from Lleywin (sp?) to Bravil a warthog began chasing us. I didn't realize what it was, but the enemy music was playing. I stopped to look and saw nothing. I finished riding to the stables and dropped my unicorn off and closed the gate. Next thing I know the Bravil gate guard goes rushing past me. I turn around to find my unicorn out of the pen fighting a warthog. I join in the battle, but once the warthog is dead it doesn't stop.

The guard starts attacking my unicorn. Then the stable owner and her helper join in the fight. Before long the Bravil guard is dead and the stable people begin running in fear. They both flee to the stable home where my unicorn is trying to enter through the door. To top it all off, I made my "biggest fan" from being a tournament champion follow me to Bravil and I stuck him out in the stables to wait for me. As I chased after my unicorn during the melee I saw my torch-holding buddy running away down the bridge to the castle gates.

I couldn't ride the unicorn even though it was standing still so I entered Bravil briefly and then came back out and found it walking around calmly. I rode it back into the stables and parked it. The stable dude was quite friendly again. I then checked out the dead guard and looted some Bravil castle keys.

My questions are: 1.) How common is this type of engagement? 2.) Will the death of the castle guard or the running away of my "biggest fan" mess up any future quests (should I load from an earlier save)? and 3.) What will those keys allow me to access?

Thanks for any assistance in helping out this noob!

Hahahhaa... I love tales of the homicidal unicorn.

Basically, if you draw your weapon in range of the unicorn (or get aggro, basically), the unicorn turns murderous.
