Before The Feasts

I was careless in the training grounds today. Should have expected today to have gone how it did... At least I got to see Yamna before I somehow got transported to a mountain area, far from where Karak said we were meant to go. I was alone.
 
My amulet, which I've had for as long as I can remember, has surprised me today.
 
It was freezing cold on the summit of this mountain. Luckily I found a door after scratching on peculiar frost... preserved dead body aside. I identified the runes on the door as being the same as the ones on my amulet... as I took out my amulet and slowly directed the face towards the door, it opened. I entered the cave, where there was a chasm alluding to lower areas - destroyed pillars barely visible below. I found a pressure plate that activated spiral stairs leading down. Upon investigation of the pillar, an Ice Mephit caught me off guard and attacked. I discovered that they are weak to blunt damage - I shattered it quickly, though not without taking some damage.
 
Not long after, a door with a face carved into it spoke to me. It caught me off guard, telling me that it hadn't seen anyone else in a long time. It had no idea how it got there, but knew it was created to contain something bad. It didn't have a name unfortunately. It didn't know how to open, either, but upon questioning, it responded with the word "Open" and thus opened, revealing its mystery. A dark, foreboding darkness threatened the air.
 
I found some flint and sparked alight the torches, lighting each one, and slowly headed into the desolate spiral staircase.
 
There, amongst a frozen Frost Giant, I met someone, but before I could say anything, we were attacked by another Ice Mephit. We took care of it quickly, but as soon as it was over, the Frost Giant spurred to life. My friend stayed behind, beckoning me to run. I did, and barely made it out - the terrain was rough, but I managed to escape by climbing pillars and getting out of concaved stone. The whole place was crumbling in on itself.
 
The Frost Giant was out without missing a beat, and caught up with me, almost hitting me - but my friend somehow returned, and pushed me out of the way.
 
Then, an avalanche - the Frost Giant lay buried in the snow, about a mile down.
 
My friend, having saved me... entered my amulet.
