A trap holding thousands of captured bijou and the threads binding them, dropped into the Nothing and deactivated.
Justice Light kept the Bijou Trap for exactly one purpose. When his legendary trap toppled, the Bijou Trap fell through the permanent portal into The Nothing, carrying with it the thousands of threads still connecting it to the Bijou of The Twelfth Floor.
The system announced that the Bijou Trap had deactivated and all captured Bijou were freed. Their unbreakable lines drew four jumbled, confused planes together and tightened into a flower pattern, and the darkness at the center of it broke apart — the mechanism by which the Nothing itself was shattered.
A trap device trailing thousands of threads, each one still tethered to a bijou far away on the twelfth floor.
Half of the two-part device that broke the Nothing, supplying the threads that pulled four planes together.
