"Gleaming as bright as the day it was made although it was quite old. The head was silver, wrapped in intersecting bands of gold that had runes etched into it. Small gems dotted it here and there. It was altogether a thing of beauty and power."
Magni told Anduin that the mace had been in his family for "several hundred years", going on to say: "This was handed down through the Bronzebeard line. It's seen battles in Outland and here in Azeroth. It's known the taste o' blood and in certain hands has been known to also stanch blood."
Fearbreaker was only in Anduin's possession for a very short time. During a meeting with Lady Jaina Proudmoore of Theramore and Baine Bloodhoof of Thunderbluff, Anduin, admiring Baine's heart and selfless devotion to do what is best for his people, presents Fearbreaker to Baine. Baine accepts the mace, and later uses it in battle against the Grimtotem in the successful attempt of regaining Thunderbluff from their grasp.
Fearbreaker remained in Baine's possession until it was presented by Baine's messenger, Perith Stormhoof, to Lady Jaina Proudmoore to solidify Perith's true intent on visiting Theramore. It survives the Mana Bomb explosion later, and Jaina discovers it among the ruins. She then brings it back to Anduin.
