Jormag

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



Trivia
Drakkar's name is possibly derived from Hebrew words Drakon (Dragon) and Kar (Cold), fittingly as the dragon is frozen under Drakkar Lake.

Or It is even more possible that the name comes simply from the word Drakkar, which was a word for a Viking boat often resembeling a dragon.
