Trials and games are happening all over the Earth. Humans lost their title as humanity and receive the identity of ‘challengers’ to challenge Dark Tower’s trials and games.

September 7, 2016.

In the middle of my first trial, I received my first ability card.

December 7, 2016.

I entered another realm by mistake and encountered you.

January 7, 2017.

I was desperate. I want to meet you again. I entered another trial and forced to open the impossible mode to go into the world where you live.

April 7, 2017.

The day we exchange our promise to be together in front of the rising sun… It also became the very day I see you die in front of my eyes.

June 7, 2017.

I will not give up. I will bring you back. I will go back in time. I will find a way to slip back to the past and see you once again.

[Congratulations! You successfully passed the Dark Tower's seventh trial.]

"I wish to open the Extreme Level Trial."

[The Dark Tower is processing your request.]

[Congratulations! You have successfully entered the Extreme Level Seventh Trial.]

[The Dark Tower is prompting you to return the regression clock.]

“No.”

Cayden absorb the regression clock and convert it into one of his ability cards.

[The Dark Tower is promptly advising you to return the regression clock to the treasure hall.]

Cayden read the spell that is written at the back of the newly transformed ability card.

"Tick, tock. Tick, tock. Hear me out and see my woes. I wish to return to the day when the Dark Tower emerged."

Cayden set the clock hour back and set the pointer back to the day when everything started.

When he opened his eyes, he was back at the intersection where the Dark Tower rise up from the ground and swallowed the high rise building on the spot.

He twisted his lips and grinned sickly. “I’m back…” then the grin widened and he started laughing.

“I’m really back! Oh, Xyris. My beautiful Xyris. I will see you soon. Wait for me.”
