Here’s how it works:
Start by downloading the app from TheSombraGroup.com for Apple or Android. (It will come in handy in the future for other things as well.)
Sombra, as readers of The Dark Tower know, is the friendly-looking business front in our world for the followers of The Crimson King, a chaos god who wants to collapse the Tower that stands at the nexus of all reality.
This conglomerate blends the magic of other realms with the technology of our own, opening portals between dimensions and allowing mortals to see things that would normally be hidden from view.
With the Sombra app engaged, turn the camera to your copy of EW’s Dark Tower cover and watch what happens.
