Nico at Hogwarts

Necromancy

My eyes almost popped out of their sockets. Technially doing a hole in the ground of Hogwarts was impossible. The boy stepped forward  into the the hole and before anyone could react he dropped on one knee, reached into the heel of his boots and producced a black dagger. Umbridge let out another shriek and said

"that still is no proof"

"of course it isn't, i'll proove it if you would just shut up!" he growled menacingly. Umbridge did indeed shut up, bless him. The one thing we where not prepared for was what he did next. He slashed the black dagger across his wrist. Several girls gave littles hicupps and screamed at the blood. When the blood started to ooze from his wrist Umbridge tried to step forward, but an black mist pushed her back, a mist that had been invisible. She screamed, loudly. Her scream echoed and soon teacher where rushing in, to find Nico kneeled on the floor, blood oozing from a fresh wound, Umbridge and us, standing, watching dumbfounded. Professor McGonagall stepped forward, wand at the ready, but once again the black mist rose around Nico.

"stop, don't interfere" a strangled voice said. We then realized it was Nico

"the wall is built by my energy, if you keep interfering it shall zap my strength" McGonagall backed away and watched. Instead of trying to stop the flow his curled his fingers and straightened them. Letting the blood flow. The blood watered the stones and after a reasonable amount had fallen the boy stood

"let the blood of the son of Hades water the stones, let it convert it into a sacred land" he said chanting. Minerva tried to get closer to the boy and the mist held her back. Nico gasped and grew paler. He was saying the truth and McGonagall stepped back, reclutantly.

"let the sacrifical be used" the boy sank the knife more deep, and withdrew it, blood stained the tip. He stood and then turned the tip of the knife towards the floor. He slammed the knife down.

"I summon the ghost of Cedric Diggory, in the name of Lord Hades" he yelled. The ground opened even more. Then the boy fell to his knees. Panting. When McGonagall hurried towards the boy, the wall didn't come up. She neared the boy and when she grasped his hand, her's went right through it. She gasped and withdrew her hand
"light, I need light" a raspy voice said, belonging to Nico.
"Lumos" McGonall and neared it to the boy. His form solidified and he lurched to his feet, staggering, away from Professor McGonagal. Then a shimmer and a ghostly form flickered next to Nico. My throat constricted when I saw who it was. Ron gasped and McGonagall looked at Nico surprised.
Nico stepped forward, staggering, his stride not as confident as when he had sneered at us
"Cedric Diggory, consecrated to Elysium?" he asked. I didn't know what he was talking about, but Cedric nodded
"In the status of my father I command you to answer any question that Umbridge issues, in complete honesty and truthfulness, do you swear by your soul? Cedric Diggory" a chatter came out Cedric's mouth, but Nico seemed to understand. He turned to Umbridge who looked terriffied
"this is the proof" was all Nico said
"where you really killed by Lord Voldemort?" She asked
