Gohar is Alex Hade's sword. It is made of Gohan Platinum and is fatal to other Vaurons.
The blade is made from Gohan Platinum, from Gohar, the old Vauron Capital. When the first war commenced, Gohar was destroyed. The sword was buried under ruins, and was found by Nordeus, who prophesied that Gohar was to be used by the Chosen One. Nordeus passed it on to Napoleon, who upon hearing the prophesy, thought he was the Chosen One. Napoleon went on to wield the sword, but the sword refused to work for him. Ultimately, he was killed. Hence, in the human world there is much confusion as to how Napoleon died.
Gohar is purposed to destroy the Davesh.
