Legends link the blade with Selich the FIrst, who was said to have chipped the blade by striking down the gates of the former Star League base in Petrópolis when he conquered it in 2800. Today that base is known as the Imperial Museum of Terramatrix (“Museu Imperial”), and it resided there until all the crown jewels of Selich’s reign were stolen in 2951. The blade was rediscovered at a private auction in 2967, but promptly vanished once more while en route to the Imperial Museum.

The blade surfaced at the height of the 3040 Marcosan Crisis, when it was formally granted to the leadership of the 7th Cavalry – “The Iron Ponies” by * “The Iron Dingoes”. Recovered from the ruins of Petrópolis, the blade’s appearance promptly tore apart the Marcosan Mandate, as many of its young soldiers questioned the legitimacy of their leadership. During the fight with forces from both The Commonwealth of Nations and various other allied forces, including * “The Fold Fiends”, the strength of the Marcosan cause was shattered, and within two months, the campaign was over.

Following its revelation, large numbers of soldiers simply surrendered when confronted by 7th Cavalry BattleMechs, and quickly swore allegiance to the new regime in Petrópolis. By war’s end, the Sword had become very much the touchstone that the Bloody Hand of Marcosa wanted for their own purposes, but denied them became their destruction. Many right-wing organizations across the planet are known to deploy the symbol as well. Together with the Imperial Crown of Terramatrix, it forms the sole remaining pieces of the Imperial Crown Jewels of Selich, the last of the world rulers.
