Flight from Altenheim

Gotta right this one quickly. Don't have much time.
 
The others were out on a hunt and Nathaniel woke up with a hangover, so I went with him to get some bacon. Met this butcher, pretty nice but a bit too good of a salesman, we ended up buying this haunch of frost bear for pretty penny. Hope Kestrel was able to make use of it like she said, otherwise that's coin we may not see again. Anyway, we were coming back to the tavern when the pillock of a chaptermaster cornered us. He was there for Nathaniel to ask about the rage potions, and a ring that was also apparently stolen? I knew he'd be trouble, but figured this was Nathaniel's fight, so I just stayed nearby in case anything bad happened. The guy did have a lackey, so it was only fair I keep the numbers even.
 
The guy started taunting him about a friend that he claimed the Inquisition had tortured to death, kept rubbing salt in the wound and just generally being nasty. Nathaniel's not in a good way anyway, so I was already on edge, but with this something started happening. I was really aware of my heartbeat and this pressure seemed to build up in my chest, it was like nothing else existed but his stupid face, and I just wanted to smash it in and shut him up for good. The ants were crawling like crazy and my bones were on fire. I wanted to fucking kill him. I wanted it so bad that after a while I just couldn't stop myself, and that's where my memory cuts out.
 
Next thing I know I'm on the ground, the bastard and his lackey are dead, and Aman was there telling us to leave so he could clean up. From what I heard later we - or I, I suppose - may have accidentally started a war. Apparently I went berserk again and attacked the chaptermaster, and Nathaniel and Aman had to cover for me while I tried to rip his head off. I believe them - I can taste blood at the back of my throat and between my teeth. Aman said he'd cover up the situation as best he could, but we're being sent to an archmage's castle while things cool down here and he handles the politics, even warned us that we may never be able to come back.
 
I'm going to see if I can talk to whatever takes over when I go crazy. I am not going to let whatever this thing is hurt my friends. It's already shown that it doesn't care about them by attacking them in the tavern. Once that's done I'll send a letter to poor Borisov, to let him know I can't meet up like I promised. I just hope the Inquisition don't somehow track this back to him.
