Myloki

The Myloki were an large unknown species who warred with Humanity in the mid-21st century.

History
The Myloki's appearance, goals, homeworld, abilities and even name were unknown to Humans. Indeed, the name "Myloki" was chosen as a placeholder.

Starting in 2066, the Myloki waged a war with Humans, both covertly and openly. In 2067, New York was destroyed by nuclear weapons. The war finally ended in 2068, when a bomb was detonated on their base on the Moon. Following the war there was vast social upheaval, with both social and economic impacts.

In 2096, there was a second attack by the Myloki, with damage worldwide. (PDA: The Indestructible Man)

Trivia

 * The effect a Myloki "searchlight" has on the Earth creates matter very similar to the 'forests' on Zeta Minor, down to the haunting animal sounds and feeling of oppression. This may suggest a link of some kind.
