Glacior

The Glacior is Sir Fangar's personal royal Sword. The tooth is said to have belonged to a giant Sabretooth from ancient times. That Sabretooth's other fang is still lost somewhere in the ice, and Sir Fangar has promised a reward to whoever finds it.

Trivia

 * The reference for the blade being a Sabre-tooth could be a reference to a Sabre-Tooth Legend Beast.
