Jormag

Thought to be one of the Ancient Dragons. It is currently in hibernation beneath the frozen pond in Drakkar Lake

Drakkar in Guild Wars
"Drakkar" is supposedly the dragon found slumbering below the frozen lake in Drakkar Lake. The creature resembles something similar to a Plesiosaur than an actual, winged dragon.

It also seems that a glow appears on characters when standing above or near it's head.
