Tyron!

Merlin followed Haliman, passing through several hallways. Finally, they stepped into another illuminated gateway and found themselves in a dreamy subspace. The sky was pitch-black yet glittered with starry sparkle. It looked very bizarre. 

Haliman greeted a corner of the void reverently. "Sir Tyron, Controller Merlin has arrived!" 

"Very well, you may go." 

A faraway voice sounded. It was slightly stand-offish. Haliman glanced at Merlin once again, then lowered his head and departed respectfully. 

Merlin looked around but could not see anyone in this subspace. It seemed like every corner was filled with a foggy mist. Merlin knew that this was Sir Tyron's residence, so of course, it was extraordinary. Not to mention, Merlin had just become a Controller and even the Medium Cosmos Controllers would not be able to properly discern this place.
