Tough and smart as a dragon should be...but we prevailed in the end. Perhaps taunting him by making a show of bagging up his treasure was not our best foot forward?
The dragon's lair had a number of exits and we chose one at random.
It had a room with a flying Iron Golem in it. After Lazurin melted it with a few acid blasts we continued down the passage to find a pair of circles. Teleport circles to be exact. The blue one took us to a red one. There we found about a dozen people who tried to kill us. I discovered a new use for the whip, removing Mirror Image spells.
This new room had two pair of teleport circles, the first pair we tried had more scrubs. The second had a red woman and a gargantuan demon. This made Gallond very happy.
The red woman took flight and began pelting us with spells. Gallond charged the demon and dispatched it after a furious exchange of blows. After grounding the flying woman Asa finished her with a flurry of strikes, only to have a mystical mark appear on her forehead. It was the Sihedron Rune of Wrath. I believe that it transfered itself from the woman to her killer.
We returned to the central chamber and chose a different direction. These new halls are redolent with necromancy. Likely dedicated to the Sihedron Rune of Gluttony, due to all the skulls having scraps of meat clenched in their teeth.
However after a few rooms filled with skeletons and zombies, a single clay golem and some paltry gemstones I am wondering if this wing of the complex is abandoned. Perhaps only the areas with surviving Runelords are still inhabited. Although this would mean that, in addition to Karzoug, Alaznust is still in this world.
