The Siege of Arroyo

(Autumnre 11th 3124 - Lune 14th 3124)
One evening, in the twilight of the mountain's sunset, there was a great light that arose from the cliffs in the west. It bathed the town of Arroyo in the brightest, purest light. A backlit silhouette arose from the glare with great horns and wings, raising his arms high into the sky as if emerging from a long slumber. A voice boomed from the figure. He said "Come and see!"
The great light then rained down on the village. Smoldering balls of fire and molten iron indiscriminately dropped on the townsfolk and their lands alike. Much of the town was reduced to ashes, including its residents. Many attempted to flee into the mountain where an old mine could offer them shelter. People of the town used baskets and tables to shield themselves from the assault as they made their exodus. Some were able to avoid the torrential downpour. Many who did were picked off the streets by winged beasts snatching them into the sky. Many were dismembered and devoured in the chaos. Children snatched from their parents, cast ablaze, and hurled towards their families to defeat their escape.
Some 900 survived to the Crichton Mines. More than half the population was decimated.
As they recovered, they were met by Kostya, a hermit who had been living in these mines for many years. He welcomed the refugees. Being a druid from the Circle of Spores, he was able to provide food and water for them. The siege continued for hours and when the flying monsters drew closer to the mouth of the mine, Kostya sealed the entrance to the mine. They would wait out the siege.
Days passed and they could still hear the tumult of a raining inferno. At the mark of one month, there was a level of stability in the mine. Living quarters were arranged, communal meals were prepared, and they've even arranged a school for the surviving children. The former population of Arroyo lived in the Crichton mines wondering if they would ever escape or if the demons would find them first.
