Ice Dragon's Lair

Description
The Isle of Frost Dragons lies north of the main Serpent Isle, and is the home of the frost dragons.

The origin of ice dragons on this island, and the multitude of tunnels that course through it, were the work of the enchantress Drogeni. The ice dragon unumbers may have been still small because they had only been present for about two hundred years. Numbers had been kept even lower due to (mostly true) legends of a treasure being hidden there--a treasure which has only increased in size because of all the slain treasure hunters.

Only the Gwani speak of ice dragon blood having incredible healing properties, but they hunt dragons for their blood only as a last resort.
