Builder's Towers

Builder's Tower is a side quest in the The Descent DLC for Dragon Age: Inquisition.

"A worn model of the Builder's Towers stands in the Darkspawn Warrens."

Acquisition
To trigger the quest, read the book found in the chamber southwest of the rune-warded gate in the Darkspawn Warrens. It reads as follows:

"Builder's Towers

The words on every page in this book have been crossed out. Spidery, scribbled notes fill the margins.

Builder's Towers, such an old game. Not just for children, no.

Big cannot cover small. Left moves right, piece by piece.

They'll never know. They'll never find what happens when the towers move. I found it, but I have no need of it anymore."

Walkthrough
This puzzle is a simplified version of The Towers of Hanoi.

To complete the quest, disassemble the tower and reassemble them on the far-right post. Remember that a larger disc cannot sit on top of a smaller disc.
