Absolution

Absolution was a great magical weapon, famous for its role in the Legends of Tyrrus, when it was wielded by Gaius Lestrade.
Absolution is an ornate greatsword, decorated with draconic symbols. It was one of the most powerful weapons in the world, but it was created with a massive sacrifice. Within the gem of Absolution's pommel is stored the soul of a dark dragon, Vendrikyn.
When the wielder of Absolution willingly gives up some of their own strength and life force to the blade, it becomes empowered, with the power to kill almost anything with a single strike, and cut through any armour. The sword was instrumental in slaying many Black Legionnaires, including the infamous Sir Zeylin.
Absolution was shattered when Gaius struck Zaikerik the Betrayer with it, simultaneously freeing the soul of Vendrikyn within. Though it did not kill Zaikerik, it injured him, and he now permanently has a shard of the blade stuck in him.
Shards of Absolution still hold a portion of the power of the legendary blade, even long after the soul of the dragon within had departed. These shards have spread all across the world.
