The unknown blade, which only lies in the core....
It is said, that it would unleash ultimate powers, that nobody could resist, ever.
But those who unlock it... get cursed...

====*The story of the unknown blade*====

A few years ago, there was a squad, called "The Delta Squad". Alpha Squad were working with them. One day, both squads researched more about the core. They have detected an unknown source coming from the core. So Delta Squad decided to make an attempt to risk their lives just to go to the core and find the unknown secret.

"Already squad, make sure ye got a rope tied behind your back. We don't want to get cursed like the other knights who decided to go down to the core"

The unknown blade was locked, and anybody who had gone near it and made an attempt to take the sword, would be cursed... forever. Alpha Squad tied a rope behind the backs of the Delta Squad. When Delta Squad reached the surface of the core, they immediately lost contact with a few knights. The surface was black with smoke. After, they have found an orb. The captain of Delta Squad raised the orb up high.... But then, the smoke lifted, and a few members of the Delta Squad disappeared. There was also a static sound. All they were able to hear was "...Help...".

After, the core surface has started to open. Delta Squad fell into the core. The core surface closed. "Squad. Are you ok? Make sure to stick together because we lost a few men. Got that?". All Delta Squad was able to see was the cursed sword. After, it disappeared... As soon as it did, the whole squad disappeared, except for the captain. "What happened? Well, I guess I'll have to get it..." The captain went ahead and saw a ruin along with the statues of the unknown blade. Then, he saw the actual blade.

There were dead knights, so he decided to get the blade. Then, he saw... the cursed knights. "What happened? What's with you guys?". They weren't acting like themselves, but acted like zombies. The captain quickly grabbed the sword and decided to run. But, when he swung his sword, he was doomed. He was cursed and couldn't move as he was cursed and a cursed zombie. The core started to react. It was shacking. After, all the knights fell down, and passed out. "......"

And so, Alpha Squad were the only ones at the core, and began to start their research at the core.
