Accidents

The eagle!

The ball of paper!

The eerie smiley face!

Hilton!

The guardians of the Witch's Legacy!

The dome clocktower!

The moment when Hilton revealed the shining red smiley face in the sea of flame, every single clue pieced itself together and formed a complete picture.

"I see! Selection, test, and acceptance…" Kieran muttered.

Now he was quite sure that if he had entered the door back in the dome clocktower, he might have become a guardian of the Witch's Legacy.

But…

Was the selected timing really done at random?

Kieran thought of the eagle and swiftly discarded the thought from his mind.

The eagle was obviously well-trained, how could a well-trained eagle pick candidates at random?

It might very well be the eagle trainer's choice, so who was the trainer?

A fairly impossible thought appeared in Kieran's heart.

"Now you get it? It's too late! You will pay for Tyler's life!"
