Noon the next day...
A figure appeared in the Silva Duchy capital skies and while shrouded by mystery especially concerning what gender it was, the figure waved its hand and causes the opening of a giant portal in the sky.
There was a deep rumbling that many could hear coming from the portal and then it began to rain boulders... Large boulders all lines with fiery lines.
The moment the boulders hit the ground, they all morphed into large monsters who widened their maws and let out roars that while potent with the lack of a proper thinking ability presented an image of unabashed savagery and might.
Now, while these were the average folks living in the Duchy capital and had been on the streets at the arrival of the monsters, they were still mostly cultivators who had the strength to either fight the monsters or get themselves to safety.
