Scene 5: The Crystal Cage
First of all, Sir Roland, following the suggestions by Garl and Rorn, touches the Threshold with the top of the silver mace, holding it in a way to ensure he can never touch the flat, semi-translucent surface of the gate.
The mace quickly sticks to the surface of the Threshold and is sucked into it. Sir Roland tries making some resistance, but the mace doesn't yield and is sfitly incorporated into the surface, while, on the other side, you see a lot of movement.
Eventually Sir Roland leaves the mace and it goes right to the other side, where youc an't see it clearly anymore.
You have the impression that, after this operation, the Threshold became a little thinner and perhaps more transparent then before.
Sir Roland, despite the cold, is sweating: "Maybe it wasn't powerful enough? What shall we try next?"
