Note: Sorry for the lateness cause I'm been really busy with school. On the plus side, this chap isn't really finished yet, and to answer some of your questions, The Hero's stone is a portkey, yes, but I did overlook the fact that the portkey comes along with you. xP .
Uchiha Itachi had packed all his essentials last night. Kunai, shuriken, smoke bombs….any ninja weapon he knew could be brought along. He knew that he would be gone for quite awhile, so he brought his ANBU uniform along. Knowing that it'll be a long trip, Itachi also brought rations. Who knows what kind of food would they eat along the way? He also brought a long black cloak with him.
All he needed to do was say goodbye.
Itachi opened the sliding door to their living room. Sasuke was there, eating a bowl of cereal haphazardly while their mother wiped his mouth. Their father, Uchiha Fugaku, was currently reading a newspaper. Itachi cleared his throat.
"I am going now." He said. Fugaku grunted, a sign he was okay with it. Sasuke got up, gave Itachi a hug and sat back down. Mikoto stood up, went to the fridge and opened it, clearly looking for something. "Itachi, come here."
Wordlessly, the Uchiha heir walked forward. Mikoto turned and gave him a bento box. Itachi accepted it wordlessly as his mother spoke softly. "You'll be going now." She said, and hugged Itachi, who did not return it. "Good luck, Itachi-kun."
"Hai." Itachi said, stowing the bento box into his pack. He formed a seal and his mother stepped back as he vanished.
The Hero's stone was a sacred place to Konoha. Names upon names of the most loyal of ninjas who died for their country graced the sleek black surface. Itachi appeared behind Kakashi, who was staring forlornly at the black stone. Dumbledore was also there, hands tucked into his huge robe sleeves.
"Well?" Dumbledore asked. Itachi gave a nod and glanced at Kakashi. The ANBU gave a distracted nod and knelt down before the Hero's stone, touching it gingerly with a hand before withdrawing like he was burned. Itachi stared at him for a moment as Kakashi spoke.
"The Castle is a huge place." He said. Kakashi stood up glanced at Itachi. "Don't forget to follow the boy, alright?"
Itachi gave a nod. Dumbledore went to the stone and tapped it with his wooden stick. The stone shone for a moment. Dumbledore turned to look at Itachi while keeping his hand on the stone. "Come."
Walking closer, Itachi held the stone, and felt a jerk at his navel before he was lost in a world of bright colors and a constant spiraling motion.
Kakashi stared at the place where Itachi and Dumbledore were before walking away.
Harry Potter tucked his hands into his pockets as he walked along Grimmauld Place. The muggle houses were silent now, the occupants deep in sleep. Harry casually walked down the lane, whistling some tune taught to him by Sirius. Harry suddenly felt a familiar cold invade his senses. Turning rapidly, Harry whipped his wand out, expecting to find a Dementor.
There was nothing behind him. Fidgeting, Harry turned around. A Dementor reached out and grasped Harry's shoulder, pulling him close. Harry dropped his wand in shock. The cowl covering the Dementor's face was gone. A poker faced skull neared Harry's face, mouth opening for a kiss. It was cold….so cold….
Harry! No! Take me instead, don't kill Harry!
Someone held Harry, pulling him away from the Dementor's clutches. There was a cry. Harry couldn't remember what the newcomer said. Darkness filled him, and he collapsed.
The trip with the Portkey ended with Itachi hurling in the nearby gutter. Dumbledore would've sympathized, but not now. They had to get to Grimmauld place. Itachi would be staying with Harry in the meanwhile before September. However, when they got to Grimmauld Place, Dobby had stated that Harry had gone for a walk.
The ANBU operative cursed and put on a black cloak that hid his bone white suit and put on a vaguely familiar Weasel mask with red stripes. ANBU Weasel had taken out a sword, buckled it to his side and rushed out the door.
Dumbledore was left behind to tell Dobby to seek out Sirius and Lupin.
FOOL! The word rang in Itachi's mind. IDIOT! STUPID IDIOT! GOING WITHOUT A GUARD!
There. The boy! Itachi put on a huge burst of speed as he drew his katana from its sheath. He widened his eyes and nearly shouted as he pulled the boy away.
"Sharingan!"
The shadowy form was suddenly viewed in a different way. Chakra coursed through this being, an intense flow that made Itachi blink. He aimed for the heart of the chakra, the head of the dark being that made Itachi feel cold….oh so cold…
The more he got near it, the more he began to hear voices. The voices of the dead were crying out to him; all those he had killed.
Help me, please….I'm cold….
Don't kill me! Please don't!
ANBU! No!
Itachi shook his head in confusion. Why? What were these things…?
The Dementor neared, opened its skull mouth and screeched. Itachi dove his sword through and through the shadowy body. The Dementor screeched, but not before nearing Itachi's face and opening its mouth again, breathed its last. The thing's breath smelled like a graveyard. Itachi flinched, but the damage was done. Itachi felt himself feel cold; all the warmth was stolen from him. Lines appeared on his face as Itachi himself succumbed to the dark.
