Urn of Terenas Menethil

The Urn of Terenas Menethil once held the ashes of King Terenas Menethil II after his death at the hands of Arthas Menethil and the Undead Scourge. The urn, forged by dwarves and magically enchanted by the mages of Dalaran to preserve ashes indefinitely.

As part of a plot to summon the demon lord Archimonde, the dreadlord Tichondrius ordered Arthas Menethil to revive the necromancer Kel'Thuzad. However, a being of Kel'Thuzad's power could only be reanimated using the energies of the Sunwell, and Kel'Thuzad's remains were too badly decomposed to survive a journey to Quel'Thalas. Tichondrius therefore charged Arthas with stealing an enchanted urn from the Order of the Silver Hand, in which the remains could be stored and protected. After killing Uther the Lightbringer, Arthas dumped his father's ashes out of the urn, then had Kel'Thuzad's remains placed within inside it.

After defeating the high elves, Arthas poured the necromancer's remains into the Sunwell, defiling it and allowing Kel'Thuzad to be reborn as an undead lich. It is presumed that the lich born from Kel'thuzad's remains surrounds the urn, though the urn may have been discarded in favor of a more potent phylactery.
