In the catacombs under the heart-shaped rock in the desert….
Suitably warned by the winged lion, we resumed our exploration. We found a room which apparently had been occupied recently -- a cushion appeared to have been sat on, and there was a bowl of fresh fruit. We also found several sarcophagi and artwork depicting scenes from the Calamity.
We opened the sarcophagi and found the remains of well-to-do Elves, apparently architects and builders. We questioned whether or not to loot the caskets, and decided not to.
We went back to the large cavern where we had found a dragon before. Val foolishly decided to walk through the mirror in the center of the chamber! He disappeared, as if he'd walked through an open door. His servant threw a rope around him and yanked him back.
After much deliberation, we all went through the mirror. A large luxurious chamber! Three richly-garbed people and two armored guards awaited us there, looking at us quizzically. Jaman-Sa Org (ruler of Ankharel) greeted us -- apparently this place was the Cerulean Palace! The ruler asked us to not return to the catacombs, and to not speak of the matter to anyone. We left peacefully.
As we were walking the streets, we heard alarms! A prison break!
