Der Eisendrache — The Secret Room and the Plunger

Der Eisendrache’s clock tower sits frozen at 1:15 until a Ragnarok DG-4 trap set behind the mechanism starts it ticking. Stop it at exactly 9:35 — the numbers write themselves — and an orb appears above the Undercroft pyramid; wall-running the right circle during anti-gravity throws the runner back in time to a hidden Group 935-era room.

Spoilers: low
