Equestria's Anomalous Winter

Survivors: These are ponies who simply found themselves victims of the situation and were able to survive the most difficult years of 1009-10012, when all of Equestria was at the peak of instability. Now they wander around Equestria, sometimes in groups, sometimes living in small, makeshift settlements. Their goal is simply to survive until the next day.
The Reddiers: a group hostile to all. They shared the same fate as the survivors, but decided to choose a different path for themselves. They decided that in such a cruel world you can only survive if you yourself are cruel, and therefore their main source of food and survival became other ponies, mostly defenseless ones. They strip them completely and often kill them.
Slave traders: essentially the same raiders, but much less cruel and more intelligent Their goal is not theft and robbery, but the ponies themselves, which they can use as labor and as an object for sale.
Marauders: They are almost like garbage collectors: they can drag away everything that is not nailed down and steal it, if possible, in order to then sell it to someone else.
Hunters: They mostly travel alone and don't stay in one place for too long. They obtain meat and skins honestly, and then either eat the meat and make clothes from the skin, or sell everything.
Mercenaries: a ruthless faction whose members know their business. They usually hang around in some settlements and kill to order for good money.
Secret scientists: It is a secret organization that was created with the goal of bringing Equestria back, and to do this they explore the area and study anomalies.

Twilight Sparkle was in a castle that was covered in ice and she was in a depressed state. After this, all the friends were broken and were forced to disperse. Pinkie Pie went to her family at the stone farm, where everything was as dreary as always. Rainbow Dash Fluttershy and Scootaloo tried to fly to the southernmost part of Equestria in hopes of finding at least some warmth. But when part of the journey was completed, Fluttershy realized that she was not able to cope with such a route and she said goodbye to Rainbow Dash and Scootaloo, remaining in the forest among nature and surviving animals. Rainbow Dash and Scootaloo flew further, but in the very south of Equestria they did not find the expected warmth, but they did find a small settlement, which soon turned into a raider settlement and Rainbow Dash with Scootaloo became part of the group. Applejack, Applebloom and her entire family went to Appleloosa, because a lot of farmers had gathered there, who were trying to save their crops from the cold by covering them in every possible way. Rarity and Sweetie Belle went to Manehattan, where they later became part of one of the surviving groups.

After the death of two princesses, Princess Twilight Sparkle took over the leadership of the country in 1009 and came to Canterlot Castle. She hasn't said a word since Princess Celestia and Luna died. There was a crown on her head, and on her face there was only sadness and open despair.All that is known is the last decree she issued at the end of 1009, which stated that Celestia and Luna were canonized as holy martyrs. She clearly wanted to ensure that despite such a lawless murder, Equestria never forgot about its true princesses. Since then, nothing has been heard from Twilight, and her castle is completely covered in ice. She is probably still there in complete solitude and a depressed state.

A country once ruled by two princesses, but in 1009 everything changed when they were killed by unknown ponies. The country was gripped by an abnormal cold due to the death of Princess Celestia, who once raised the sun, and Princess Luna, who once thought the moon. Because of this, the moon and the sun began to rise and fall chaotically, and the sun stopped warming as it had before.
