London – Authorities have issued a city-wide lockdown following the catastrophic destruction of the Obsidian Mirror at precisely 14:37 GMT. The event, which occurred within the confines of the Brutalist headquarters, has triggered a localized temporal distortion, creating a visible void and prompting widespread panic amongst staff and security personnel. Initial reports suggest the mirror, a device of unknown origin and purpose, imploded with a force equivalent to a small nuclear detonation, leaving a gaping hole in the facility’s central chamber.

The Obsidian Mirror, reportedly a prototype developed by the enigmatic Dr. Silas Blackwood, was believed to be a conduit to… well, no one was entirely sure. Blackwood himself remained tight-lipped about its function, referring only to it as “a key to understanding the architecture of time.” Witnesses describe the mirror as a perfectly smooth, black obsidian surface, emitting a low, almost subsonic hum before its sudden disintegration. Immediately following the collapse, the air shimmered, and a swirling, grey void – approximately 10 meters in diameter – materialized within the chamber.

“It wasn’t like an explosion, you know?” recounted security officer Marcus Bellweather, visibly shaken. “It just… *became*. Like something ripped a hole in reality. I saw faces – faces that weren’t *here* – flickering in the void. It was… wrong.” Several individuals within the building reported experiencing disorientation and brief flashes of memories that didn’t belong to them.

The immediate consequence of the event is a complete disruption of the building’s internal systems. Power is intermittent, communications are down, and all personnel are being evacuated under heavy guard. Dr. Alistair Finch, Blackwood’s chief assistant, managed to escape with a single, heavily encrypted data drive. “Blackwood was obsessed with the idea of ‘temporal resonance’,” Finch stated in a brief, frantic message relayed through a secure channel. “He believed the mirror could allow us to… step outside the linear flow of time. God help us all.”

Authorities are currently attempting to contain the void, utilizing experimental energy fields, but their efforts have so far been unsuccessful. The long-term implications of this event remain unknown, but experts are warning of the potential for widespread temporal instability and the possibility of further, unforeseen consequences. The city remains under lockdown as investigators scramble to understand the nature of the Obsidian Mirror and the terrifying void it unleashed.
