Ice Dragon's Lair

Description
The Isle of Frost Dragons north of the main Serpent Isle is the home to said Dragons.

The origin of Ice Dragons on this island, and even how the tunnels were dug out, were in fact the work of the enchantress Drogeni. Because the Ice Dragons have only been on this island for roughly two hundred years, it would account for why there is not a large number of them. 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.

The Gwani speak of Ice Dragon blood having incredible healing properties, but it would seem only they are aware of this and they hunt dragons for their blood only as a last resort.
