The Holy Empire of Man used every means conceivable to gain power, including some very esoteric weapons. Constructed during the War of the Empires for the Purification Fleet, the Emperor's Eye is a gargantuan star-ship with the power to incinerate entire cities using the focused light of a star. The Emperor himself was on hand for the dedication ceremony when construction was finally complete.
The Emperor's Eye saw extensive use during the War of the Empires, burning cities that refused to join the Empire. It saw some use during the War of the Gods, but not as much because relatively little territory changed hands during that conflict. It was destroyed in a raid by rebellious imperial subjects before the start of the War of Galactic Unification.
The center of the ship is a refracting lens approximately 100 kilometers in diameter, surrounded by a ring containing the ship's systems. The lens is constructed of smart-materials, and its shape can be precisely controlled. When not in use, the lens is deformed, so as not to focus light.
