=== The Lion Sword ===

Throughout his travels the Lion was known to use a red blade of excellent quality. When the Lion was put into his coma, his sword was interred alongside him in the Rock, ready to be wielded again by its master should the Lion ever wake from his coma. That sword is The Lion Sword, a Kinebrach blade exchanged as part of the ceremony finalizing the alliance between the young Imperium and the Interex. 

It was the last blade made by the venerable master Mez-Go-Bur, who was said by witnesses to his work to have used neither forge nor hammer in his smithing, and that the metal he worked was taken from the shell of a fallen Cybernetica robot. He struck the metal with his bare fists, and as it started to heat up and become pliant the swordsmith beat all his sorrows (which were many) and his wrath (which was considerable) into the metal before him. The cherry red blade was quenched in a barrel of ceremonial oil mingled with his own blood, and on that concoction-laden blade he inscribed words of binding — banes against daemonic beings. Daemons had made his life a misery, so his blade would cut them and leave them maimed and miserable in turn with a pain that would follow them to the depths of their Hell. No matter if or how they healed the wretches would never stop hurting — as he would never stop hurting. But though he would die the daemons would linger eternally, and upon them would be inflicted a pain that would likewise linger eternally — for ever and ever and ever.

He smiled when the sword was handed over to Lion El'Jonson. He died not long after.

There are many Kinebrach blades in circulation in the Imperium and the art of making them is in no danger of ever being lost, but few are as vindictive as the ones made by Mez-Go-Bur; The Lion Sword was his last creation and believed to be his best.

There was a legend among the people of Franj: if an implement is left for more more than a year and day it will hunger for blood. The blade has been idle for too long now. Too many summers under a shroud of dust, even as its edge remains razor keen. If the old stories are true, then the Lion Sword thirsts a great deal. It would take a man of iron will to tame that blade now.
