Daring Do and the Catacombs of Causality

The Professor clears his throat and sits upright.

"Daring Do, you are currently experiencing a magically-generated simulation created from your memories. It is a simulation with precise rules," he says. "I fear I must inform you that am not truly Professor A. B. Ravenhoof. I am a realistic simulacrum constructed from your memories of him."

You blink a few times. "Okay, I don't understand any of that," you admit.

"You are currently experiencing an enchantment that places you in this odd virtual reality. The enchantment draws upon your memories to construct the puzzle," he says.

You groan. "Puzzle? Oh, great."

He nods. "I thought you liked such things?" he asks.

"I like them well enough, but not when I'm currently dying in a pit."

"Don't worry, you're not," he says, with a smirk.

Return North to the hallway.

Ask him what he means by that last bit.

Ask him why he, specifically, is here.

Ask him about the books he's looking over.
