Black Markers
Within a subterranean living room, all eyes and ears are glued to the television, watching and listening to the greatest global event in history of humanity.
It is being unfolded across the planet.
More than a thousand of these black obelisks are deposited onto the planet by the numerous starships hovering in the sky and in orbit.
These strange alien structures are placed at an equal distance from each other for maximum coverage and effectiveness.
The vast ocean of the planet did not impede their emplacement whatsoever.
Untold power radiates from each of the spiraling black towers, pulsating and emanating ominously.
It is mostly for effect, but any kind of electronic equipment that get too close to these alien towers will be instantly fried by powerful electromagnetic pulses.
Several helicopters have learned this painfully and fierily.
