Obscurers are technological devices in the Lost Cities, created by Lady Iskra. They hide a person or a small group (if they are close together) from others by bending sound and light around the user like a force field. All anyone can see or hear is wind and a slight distortion in the air, like heat waves radiating off the ground.
They are used by Sophie Foster and her friends when they visit Paris and a few other times when they want to hide. The Neverseen used them in Paris to hide themselves, Sophie, and Dex from human eyes during a fight on the bridge in Book 1.
