Mag'ladroth

Mag'ladrothis a canon entity, detailed here on Lexicanum. This article provides additional fanon details and history.
Mag'ladroth, also known as the Void Dragon or simply The Dragon, is one of the C'tan - the god-like beings worshiped by the Necrontyr and later the Necrons. While the official Warhammer 40,000 canon leaves it ambiguous as to whether Mag'ladroth is the Dragon of Mars, defeated by the Emperor in a battle that was the origin of the legend of George and the Dragon and imprisoned beneath the oxide sands of the Red Planet before the Age of Strife, this fanon makes it explicit that is the case.
