World of Hearts: Linked as One (Book 1)

0-4: Eternal Darkness

5 kilometers away from the Japanese mainland was an island with a prison complex built on it. This prison complex was named Tartarus. It is a special prison made to keep villains locked inside and away from society. The prison was impenetrable. There is only one bridge leading to one gate that is covered by guards. There were multiple towers here as well as powerful gun turrets to repel attackers. The prison is surrounded by a wall that was made of solid steel.

Inside the prison itself were blast doors capable of withstanding high yield explosive blast waves. Inside the cells were a multitude of sensors linked to cameras and machine-gun turrets. The guards were equipped with lethal weapons and could be given authorization to use lethal force to keep the prisoners from escaping. The security system was state-of-the-art. Many of the more dangerous villains are placed in deeper cell blocks with B10 being 500 meters down below sea level. The people of the world thinks that no villain will be ever to escape Tartarus and that the prison could not be breached by any means.

But now?

The prison was a godforsaken mess. The whole place looked as if it was attacked from both outside and inside. The gate was blasted to smithereens. The guard towers were nothing but dust and rubble. Many of the facilities here had taken severe damage. The gun turrets were destroyed from some kind of aerial attack. There were even severe casualties.

The police force arrived first, followed by Endeavor and his sidekicks Burnin, Kido and Onima. They were followed by Hawks, Best Jeanist, Eraserhead, Kamui Woods, Mt Lady, Miruko, Present Mic, former number one hero All Might, and Edgeshot. They looked on in disbelief at what they were seeing. The impregnable prison complex had been breached and all there was right now was total wreckage. The heroes went looking for survivors while the police were committing a formal investigation.

Endeavor, Hawks, and Best Jeanist arrived at the B10 cell block. They saw the bodies of several guards with blood coming out of them. The bodies of these men had blood-red crystals growing out of their bodies. Endeavor could only ball his hands into fists. All the cell doors in this block were either opened forcefully or were just torn off.

"Did All for One do all of this?" Hawks asked. "Or was it Tomura Shigaraki who did this?"

"Either way... this is too barbaric, even for someone like All for One," Jeanist said. "And Shigaraki would have simply used Decay or any of the stolen quirks he gained from having All for One's Quirk Factor implanted in his own body."

"And there's no way a High End Nomu managed to get this far in," Hawks said.

Endeavor went over to the bodies and examined them. The guard's hands were cut off. When they were cut off, these crystals must have sprouted out of the wounds. Then more crystals began to burst out of the guard. The rest of the upper arms, the shoulders, even the upper torso had crystals sticking out of him. Endeavor got up.

"These men never stood a chance," Endeavor said.

Hawks squats down and looked at the bullet casings on the floor. There were so many bullet casings on the floor that the guards had to have been in formation trying to stop their attacker from advancing. Multiple empty gun magazines littered the floor. Blood was all over the cell doors.

"Whatever or whoever killed these guys, they must have been highly durable to withstand all that gunfire," Hawks said, tapping his communicator. "Edgeshot, have you found any survivors?"

"Negative," Edgeshot replied. "All I'm seeing right here are more and more dead bodies, some of them had been torn open and... god, these men were being eaten alive..."
