Guarded

We were reviewing the requirements for the border crossing with the Elven land.

"So we need to make sure the guard here is incredibly stupid."

"What? Why?"

"We learn more about the Pepper coming in with that, the second guard with an invisibility cloak will observe how they treat the guard."

"But what if they see that guard and change their actions because of that?"

"The third guard observing with the seeing-eye spell will detect that."

"And if they notice them?"

"Then they're powerful enough to be told that they can enter."

"And then the fourth guard watches them?"

"Exactly!"
