Create an ancient sword named "Ceifadora de Almas," designed for the son of Hades. The blade is black with a deep purple hue, resembling dark obsidian, symbolizing the underworld. The blade is long and slightly curved, with a shimmering dark aura, giving the impression of an ethereal connection to the realm of the dead. At the center of the hilt is a menacing skull, its eye sockets glowing faintly as if watching the souls it claims. The hilt is adorned with intricate carvings of serpents and skulls, reinforcing its connection to death and the spirits. The crossguard is forged in the shape of bat wings, dark and threatening, enhancing the weapon's ominous appearance. The pommel features a large, blood-red gem, glowing faintly, as if imbued with the souls of the damned. The entire sword exudes a foreboding presence, clearly designed for a warrior destined to rule the underworld
