At first, Colin thought that the knight Erwin had summoned was just an ordinary one, but when the Palace guard respectfully greeted him with, "Prince Serass," he suddenly realized—
The ordinary White Tower Guard Knight in front of him was actually a member of the Roon Royal Family!
"Mr. Colin, we have arrived at the library."
Serass led him smoothly to the Black Tower Library deep within the Palace.
However, even Serass needed to produce Erwin's written order to gain entry.
From the outside, the Black Tower Library was just an ordinary three-story black spire, but once inside, Colin discovered its hidden secrets.
Perhaps as a means of defense, after crossing the gray-black tower gate, Colin's vision blurred, and the wall in front of him turned into a brown bookshelf. Looking around, everything was shrouded in darkness.
Unbeknownst to him, they had arrived in a separate small room.
The Black Tower Library entrance concealed a transportive secret.
