When fox king Aller Clawslash sets eyes on Redwall abbey as a barracks for his vast army, as well as Mossflower woods as an expansion to his kingdom (Nanta-de-kapuuna), the citizens of Redwall are captured and masacred by the day. However, help comes from the most unlikely of places; an assassin who lusts for Aller's kingdom, a tribe of shamans who frequently offer beasts as sacrifices to the "Gods", and...the legendary spirit of Mossflower Winter known as Ice-storm.
Will Aller Clawslash be defeated? Or will Mossflower be annexed to the kingdom of Nanta-de-kapuuna?
The wind blew. The fire flickered out. Mossflower Woods was covered in snow, for it was the winter season. Redwall Abbey mourned, for vermin had taken their young ones, the dibbuns. In their camp, in the woods, snow was cleared out, a smoking fire pit was in the center. On the trees hung the corpses of dibbuns, and vermin eating their flesh. It started snowing, the wind grew stronger. The vermin-made canopy above the camp blew away, the tents were ripped off the ground. Screams were heard all across the camp as vermin flew around, tossed around by the wind.
"It's coming from over there!" A rat screamed, pointing in the direction of a small shrine as his life was snuffed out by a rock tossed by the wind.
It was all over. THe storm retreated, the battle was won. THe shrine in the distance stopped glowing, and the dead dibbuns (Somehow not affected by the storm) faded away.
"Rest well," a deep voice said. Redwall abbey was sudenly covered in clouds.
