"You see?" Voldemort called, pacing back and forth behind where Harry lay, "Harry Potter is dead! Do you-" he was cut off by a massive wave of dark power, centered between the castle and the forest where the Death Eaters were standing.
The shadows congealed and a figure in black robes stepped out from them, "Tom Marvelo Riddle," Voldemort started at the familiar voice, "you have a lot to answer for."
The wizards scoffed, but Voldemort started looking panicked, "A-ambassador! H-how is the olympian's universe holding up?"
Mutters and whispers broke out among the wizards. 'what universe?' 'why is you-know-who so afraid?' 'is that Death?'
"Fool." The speaker pulled a black-bladed sword from his sheath, "You thought that running to Hecate's splinter universe could save you from Father's wrath?"
As the black-robed figure made his way towards the crowd of Death Eaters, he dropped the hood on his cloak. Everyone gasped as the mysterious figure was revealed to be a pale fourteen-year-old boy.
Voldemort pulled a black wand from the folds of his cloak and it morphed into a long, double-bladed sword emitting dark purple vapor, "You are alone, with no friends and no help. You can't take me."
"I," the cloaked figure stated, drawing himself up, "Am Nico Di Angelo, Son of Hades, Ambassador of Pluto, Hero of Olympus, Ghost King, Retriever of the Parthenos, and by the authority vested in me, you are under arrest in the name of Death and Hades."
The shadows around Voldemort hardened and became tentacles, which grabbed the dark lord and dragged him to the ground. A wave of shadow encased him, and he vanished, never to be seen on the earth again.
