The Castle of Doom    

Xin held his breath anxiously as he watched others enter the gate. His greatest fear wasn't just the risk of blowing their covers but whether Hilda could successfully cross the teleportation gate.

When his turn finally came, the transition was seamless. The virtual world shifted as he crossed the threshold, and the Arch Gate closed behind him with an ominous resonance once all of them had entered.

Silence fell like a veil over everyone as they suddenly found themselves in an entirely different dimension.

Xin immediately turned to look behind him, sighing in relief when he spotted Hilda, who wore a clueless expression, seemingly unaware of his worries.

"Good thing you can cross that gate," he whispered.

Hilda beamed. "Like I said, I don't have that restriction on me."

Xin nodded, silently thanking the developers for overlooking such crucial details. 

But then again, in the first place, no NPC would willingly venture into this realm.
