Chilling Perils      

"Hikari, did you find the exit yet?" Midnight Duchess inquired.

"It's that door," Yuzuro pointed toward a metallic door at the very end of the room. "But it seems locked, and we need some kind of key."

"Does it have a knob?" Xin asked.

"I don't think so."

"Then we only need to find the key," Midnight Duchess said, doing her best to reduce the Snowworms' numbers that threatened to overwhelm them.

"Is this it?" Xin dangled a frosty-looking key in front of the crew, acquired by his golems while they killed the Snowworms.

"Agh! Lord Schrödinger! You already found it?" Yuzuro exclaimed in glee. 

"My golems got it when they killed a bunch of Snowworms."

"I'll create a path," Midnight Duchess declared, positioning herself in front of the Snowworm horde that blocked the door. "You go and check if it's the key to the next room."

"What if it isn't?" Xin asked, his expression unchanged.
