Thrym is one of the largest creatures in World of Warcraft and can be seen from very far away.
Thrym's name is also based off of the giant in Norse mythology that was particularly known for stealing Thor's hammer, Mjölnir.
Thrym is one of the 3 mobs that can be easily seen from a good 10,000 yards or more. The others are Putridus the Ancient, who can only be found in Icecrown and Mobus who patrols the Abyssal Depths.
