Alex was interrogating Dio in his cabin. He threw a leg up onto his desk, cluttered with a various amount of different papers and other things, as he carefully regarded the lord of house Eraclea with keen eyes. However, Dio didn't seem the least bit bothered by the look. He walked freely around the room, glancing at a picture of the Silvana that hung on the wall, and leaning down to peek at a photograph placed on the table.

"I like this room! It's really unkempt and dirty."

Seeming more honest than sarcastic, he cheerfully observed some plaster stains on the wall.

"What does the scion of the Guild want on this ship?" Alex said, meeting Dio's gaze.

"I only really wanted to come so I could fly with Immelmann."

Alex ignored Dio's response.

"Are you here for the Exile key?"

"No way. I'm not Phalaena."

"I've heard that House Eraclea is made up of nothing but greed."

"You don't believe me?"

Dio approached Alex from behind, bringing his lips up close to his ear.

"What lies beyond the furthest reaches of the sky..."

He whispered what sounded like a piece of a solemn poem. For a moment, the air around them felt cold. Alex's eyes moved to silently look at Dio, who was smiling at him innocently.

"That's the Mysterion of House Eraclea that's been passed down for generations. Only Delphine and I know it."

"Why are you sharing such a thing with me?"

"I think you can put it to good use, captain."

Dio moved quickly away from Alex, bringing his face up to look out the window.

"Hamilton, Dagobert, Bassianus... each had their own Mysterion, passed down in the same way. But my sister purged the other families."

"Maestro Delphine's coup d'état, you mean."

"She sees it as quelling a rebellion full of troublemakers."

Long ago, the Guild was operated by a council made up of four families. However, ten or so years ago, a still young Delphine assumed the position of maestro after many sudden and complex events came together. Through instigation and seduction that gained the favor of many young people and guards of the Guild, she orchestrated the purging of the other three houses, exiling them from the Guild. Although to many it was simply called a "coup", there were some who grasped the truth surrounding that matter.

"The tradition of passing down the Mysterion through each house was stopped by the Maestro. Is her intention to collect the others?"

"Phalaena is trying to do that willfully. He thinks it will curry favor with Delphine. Because my sister thinks everything in this world belongs to her, if she could free Exile I'm sure she would be delighted."

"Do you know what the Exile is?"

"No, and I'm not really interested in knowing. Have you seen the cocoon, captain?"

Alex fell silent, tensing up somewhat as a terrible memory stored in back of his mind surfaced. The seat behind him was empty, a terrible storm engulfed him. He could feel an overwhelming weight on his shoulders. The place where his heart was killed even though he had escaped death himself, he would have to return to that place one day soon. His life's goal, to accomplish this...

Dio suddenly turned around, his silver hair swaying.

"Hey, can I go and see Immelmann now?"

Wishing to be by himself as soon as possible, Alex nodded.

"Mister captain, once you've collected all of the Mysterion, you'd better get to Exile immediately. If you hesitate, you'll miss your chance..."*

When Alex turned to ask Dio what exactly he meant by that, the boy was already gone.
