The Great Flood

The great flood was a huge flood that covered almost 24% of Xsilan land at ~10,000,000 B.C..It was a mass extinction that wiped out about 21% of ocean life and about 42% of land life on Xsilan.

Before the flood
Before the flood Xsilan was thriving with almost the most biodiversety it has had in years.They have had no nateral disasters in millions of years and civilization was just starting to slowly grow.For weeks a meteorite had been shining in the sky, but after almost 2 years of orbiting the planet it finally crashed into the Bosch ocean, just north of New Earth.

Extensive Damage
The first part of xsilan to be hit was the eastern shores of old Greifos, destroying all of ancient Roojun.The Northern and eastern parts of Greifos were completely submerged.Most small islands like New earth (Parvauria at the time) was completely submerged.The southern shores of Crassis were washed up too.Most of Kondaironk was underwater, with only small islands peaking out.The whole flood took about 2 hours before it stopped.For the next 100 years there was no civilization on many of the islands and there would be chaos and carnage due to the destruction of many cities.The ancient cities of Novis and Roojun were completely lost to sea, never seen again.

Mass extinction
Many sea creatures were washed ashore, dieing without oxygen.Today many scientists still find skeletons of old speceis on the ocean floor that were washed away on that day.This was one of the largest extinctions on the planet of Xsilan.Over 20 species had went extinct that day including Trench fish, shore moles and many others.Many thousands of people died that day, Tharrks, Humans and Jonaldos alike.

Xsilan Recovers
After the flood it took about 2,000 years for most of the land to be recovered from the sea.It took almost 800,000 years for the population to stabilize at where it was before.Almost 3 whole cities were washed out by the water, Roojun, City of Gandheard and Great Asholt(Great Asholt no longer exists).A lot of history was lost to sea that day , buildings, people , artifacts and more.There are reports of people washing up to shore, days after the flood, still alive and breathing.
