Barbarian's Log
Beneath the rotten mansion, we found a stair leading down. We descended. I was at the front, as usual, prepared to shield my party with my body, my great axe at the ready. After a while, my beast-trained senses felt a change in the air and the light. I felt we were no longer in the normal world. Just then, Wizard said something about entering the Underdark. I didn't know what that was, but she did, so I didn't ask.
Eventually, the stair widened and we came across a fancy tiled room. There were statues of cruel-faced elves and a firepit in the middle. We gave it a glance and then passed through, lighting braziers as we went. We then spent some time exploring the tunnel the wound further and further down. We found other chambers; bedrooms, an armoury filled with curved blades, a room for the worship of foul demons. The chambers all seemed recently abandoned, probably because of the chasm that spanned multiple corridors, making the place difficult to travel for the less athletic. I had to toss Wizard across at one point, but we made it past.
When we reached the bottom, the air became damp. I smelled mildew and water plants. It was a huge, misty chamber. A huge summoning circle had been built to stand over the water and its magic still glowed. Again, my senses felt something off; we were not alone. Hiding in the fog, slinking around the raised plinth towards us, was a dragon. It was massive, black and shadow-like. We had fought a dragon before, but not like this; this was something unnatural. I gritted my teeth and prepared myself, knowing I was about to have the most testing battle of my brutal life so far.
