In a fantasy world where balance and harmony are taken to the extreme, everything must be perfectly stable, regardless of the cost or price.

If a race is on the brink of extinction, they become increasingly stronger and more resilient until their numbers are up.
Conversely, if a race is dominating, their reproduction becomes more challenging, they become weaker, and their lifespan shortens.

But what would happen if a bunch of humans suddenly appeared out of nowhere?
How would the residents react?
How would the humans react?

Join our protagonist, Nivia the Harpy, on her journey to discover this world, its changes, and the humans.
