Peculiar Places: The Icy Tomb of the Hoar-Dragon
Tags:
Hidden deep in the Hanomae Tundra, a sword juts into the air, embedded in the permafrost. Beneath it, a dark shape like an elongated, massive head can just be made out through the cloudy ice. In fact, if one were able to get a view of the ground from the air, a dragon-like shape would be clearly evident.
If the sword is removed from the ice–no small feat, mind you–a sequence of events begins which cannot be averted. First, the wound in the dragon’s head rapidly closes, preventing the sword from being replaced. Next, two dull glows appear on the sides of its head as its eyes open again for the first time in millennia. The ground begins to shake as the long-dormant dragon awakens and tests its icy prison. Cracks appear in the permafrost; it is clear the dragon will not remain entombed much longer.
How does the dragon react to the PCs? How and why was it entombed in the first place? What will it do now that it has been released?

The dragon pierced itself in the head with a Sword of Petrification during an ice age to go into a slumber to wait for there to be more food. It appears that more food has arrived!
