The Helm of Domination was a magical, ornate helm (or crown) infused with the power of Domination and worn by the Lich King to control the Undead Scourge. It was destroyed by Sylvanas Windrunner to open a rift into the Shadowlands. The pieces of the helm continued to play a role in subsequent events until they were reforged into the Crown of Wills, an instrument intended to be the helm's opposite.

The nathrezim who pretended to serve the Burning Legion bore the two vessels of Domination across the veil and bound the spirit of the Lich King Ner'zhul to them. The helm, and Ner'zhul's spirit, were both sealed within the Frozen Throne from which the Lich King would control the Scourge telepathically. Frostmourne was originally also sealed inside the Frozen Throne, but Ner'zhul cast it from the throne so that it would eventually find its way to Arthas Menethil.
