Starfall Year 789, the borders of a small nation by the West Mountains.
In the Dark Forest within the West Mountains nation's borders, a swarm of vicious daemons followed their instincts and attacked a border town nearby on a winter day.
The ambush was so sudden that the border town had fallen without mounting any sort of resistance. Thirsting for blood, the monsters broke through the city walls before slaughtering most of the humans with one swift stroke and ease. They munched through bones, tore at their flesh while breathing flames and frost, turning the entire settlement into ruins.
Despite being caught off guard, the city guard had sent out a distress signal earlier, but a bunch of mysterious people in black clothes had arrived before the kingdom's armies.
