 * As you step through the portal, bright flash of white light.
 * You feel... different. But the worst news is, the room seems
 * to be collapsing on you. I mean, MASSIVE CEILING BLOCKS are
 * falling, man, do something!
 *
 * Good thing you found a place in the security system to inject
 * your custom code, maybe that can help!
