The end of an Era has come. Magic is broken. New Heroes are needed to face the challenges of the new Age!
Is Cydney in the telepathic bond? If so, I think to her: "Cydney, can you cast an Augury to Falan and simply ask him if he wants this severing to happen? He's apparently right down the hall, so I imagine he'll get the message."
She is not.
Benlin offers, "I can cast Prying Eyes and send them around the temple, but I think we already know what is happening."
Robyn asks Bigtop, "What about Malfesius? You know of his involvement. How do you plan to counter him?"
Benlin to Robyn, "Any idea if Bigtop has true seeing?"
Benlin asks Cydney, "Do you have an Augury prepared?"
Are the prying eyes insubstantial?
"I don't think he has true seeing. His breath is a cone of force that is surprisingly powerful for his size."
Cydney jumped down into the lower hallway and took off running.
Wasn't there another wall there? I believe you said she started and then ran into another wall....otherwise Benlin would have followed.
"Then I can use a programmed illusion to make him think we are still here, but actually take a few of us magically to the other side of the wall."
Cydney told you previously the alcoves are the only way to move interdimensionally in the temple. If you have something else in mind then disregard.
No Cydney ran into the wall of force above. She jumped into the hole after you opened it and yelled out "I'm coming Master." That was the end of the round before Sir William revealed you were in the circle.
