Daedalus' Slate

Origin
Daedalus was an inventor who, along with his son Icarus, was trapped on the island of Crete by King Minos, withholding their knowledge of his Minotaur from the outside world. He crafted a set of wings for himself and Icarus, warning him to not fly too close to the sun and ocean or risk falling out of the sky and drowning. Icarus, however, did not listen and rose too close to the sun, melting off the wax holding together the wings and falling into the ocean.

Effects
Integrated into the Warehouse floor, creates labyrinthine walls hundreds of meters tall in the event of mass artifact disturbance. This corrals every artifact that can’t fly, teleport, burrow, become intangible or destroy the barrier. However, if a mass artifact disturbance is causing strong electrical activity or if the neutralizing systems or damaged, the walls may stop at only a few hundred meters.

The artifact was crudely used by past Warehouses to wall off specific sections such as the Bronze Sector. Today, it is controlled by the input of an electronic code, which can also activate the slate in only specifics aisles of the Warehouse.
