Jäällätaudin - Icetongue

This ancient blade's full history is known only to the most studious Dwarven sages of the Dunheng Kingdoms. In its centuries of existence it has appeared in the hands of many heroes only to be lost again with their passing. Most recently it was wielded by Jak, a King of the Fridon people who in tales is called the Giant Slayer. He was a king of the Fridon many years ago, when his people were attacked by the giants from the Danor Mountains. He fought against them wearing the hide of a dragon and wielding Jäällätaudin, and drove them back to their burning peaks.

Goals
Cold forged of mithrail, Icetongue was made by the Dwarves of Danor to slay fire giants and all their thrall. Any creature with the fire subtype is an enemy to Icetongue, be it azer, elemental, or dragon, and it will demand their death without consideration.


Roleplaying Icetongue
Icetongue speaks in a clear, ringing voice.  It speaks Common, Dwarven, Giant and Draconic.

Flame and passion are anathma to Icetongue, and its will is deliberate and implacable as a glacier. It will calculatedly drive its wielder to confrontation with its hated foes.  Patient, unforgiving and heartless, Icetongue does not care what cost must be paid for victory.

Moving On
When Icetongue has defeated the fiery menace that it arose to battle it will leave the stage again.  Typically it is buried with the corpse of whatever hero it chose to wield it for that battle, as Icetongue's heartless drive often causes the death of its bearer even as they slay its foes.  If by terrific fortitude or cunning they win Icetongue's epic battle with their life intact he will either make them seek out a new fiery foe or else make them leave him in a desolate, icy location, such as thrust into the ice atop a glacier or hurled into a mountaintop lake.
