Many centuries ago, the Cup of Life fell into the possession of a great warlord. One night, he gathered his army before him. He took a drop of blood from each and every man and collected it in the Cup. Such was the vessel's power that the soldiers were made immortal where they stood. According to Gaius, the carnage they wrought was beyond all imagining. The army was only defeated when the Cup was emptied of the blood it contained (The Coming of Arthur: Part One).
