It is a rather plain sword, except that its blade is crafted of crystal and stone splinters, not metal. It is so large that a man from our time could only use it two-handed. Kindred archaeologists think its location is somewhere in an inaccessable chasm on the slopes of Mount Athos in Greece. Is is said pieces of Brujah's essence were mystically bonded into the blade and can be tapped into by its weilder.
Given that the sword is said to be on Mount Athos, it's worth noting that Athos in Greek mythology is the name of one of the Gigantes that challenged the Greek gods during the Gigantomachia. Athos threw a massive rock against Poseidon which fell in the Aegean sea and became Mount Athos. This primordial revolution may be an account of Troile's rebellion against their sire.
