A mask made after Dante's death which can create a wall of fire 8 stories tall whenever something moves in front of it, which is why it is always kept facing inward while in the Warehouse, so it doesn't accidentally activate. This is a reference to The Divine Comedy (Dante's Inferno) where Dante must travel through the Nine circles of Hell.

In "Time Will Tell", James MacPherson used the mask to slow Artie and Claudia down to give H.G. Wells more time to navigate the Escher Vault.
