Abandoned Wyvern Nest Hidden in the Rocky Mountains
There was a kingdom built within a natural fort surrounded by towering mountains. The prince destined to inherit the millennial kingdom met a woman one day and fell deeply in love.
The prince married the woman, and a year later, she became pregnant. However, what she bore was not a child but an egg.
The prince could not accept that his own bloodline had produced an egg, and in the end, he shattered it. She wept bitterly and cursed the land. Great birds flocked to her side and laid waste to the kingdom.
Since then, whenever signs of human presence appear, the great birds inevitably drive them away.
