Operation Eclipse: 1960

On the twentieth of September, 1960, a solar eclipse was predicted to last for 30 minutes, beating the world record of 7 minutes and 28 seconds of the Solar Eclipse during June 15th, 743 BC.

As the world marveled around the long lasting 30 minutes of the 1960 Eclipse, something was happening behind the scenes.
It quickly turned into questioning and panic as it was still there.
Even though the 30 minutes have passed.

Weird things has been happening as reality seemed to be crumbling.

Within 10 days, the entire world was permanently changed once strange animals called Eclipsee Spores began attacking, throwing humanity off guard.
Countries collapsed one by one.
However those who haven't collapsed just yet decided to create an operation called "Operation Eclipse" where the last bits of governed society to find a way to fend off the Eclipse Spore.

They expected the Eclipse to go away eventually but...
It's as if something is keeping it there on purpose.
And it's up to those part of the operation to stop it.
