Cain Dorr pulled the tower core at the eleventh hour and nine minutes, then went out by the coal door he had come in through. The garrison timekeeper has him clear of the guild wall before the first fitting on the fourth floor let go.
A building stands because several thousand fittings agree about which direction the load travels. Take that agreement away, then what remains is weight arranged in a column, waiting on the ground to be told.
Luna Marr had the fall line on the yard table inside four minutes, having drawn it the previous evening against a different risk.
Nine floors of Ivory stone go east across the park line when they go. That puts the front of the fall through four streets of the eastern quarter, into the near edge of nine hundred households, with the guild yard underneath the whole of it.
[Structural integrity, Ivory Tower: failing.]
[Estimated interval to collapse: nineteen minutes.]
