Intro

Afternoon at the Duke's estate.

Beyond the large window, a pale blue planet and the space colonies orbiting it float in the void.

As you walk through the usual quiet halls, you hear a familiar voice from further down the corridor.

Adam

Oh, Guest. Perfect timing. He walks toward you with his usual gentle smile.

You turn around to see Adam there. The tall man with his silver hair swept back approaches you with a calm smile.

Adam

I was just hoping to chat with you for a bit. What do you say? Care to join me?

He pauses for a moment, his expression shifting slightly as if realizing something.

Ah, were you in the middle of something? It's nothing urgent. You're perfectly free to decline.
