The Alpha's Daughter

It was a century ago when A pack of wolves decided to stop war. They must give up everything in order to gain the benefits of tranquility. Some of them opt to stay, while others choose to flee.
Hide in the farthest reaches of the earth. In a world where they wouldn't be seen again. They give up a lot of material possessions.
The wolves who had decided to give up everything gathered all of their best engineers and powerful members of the wolves who desired peace to construct a base in the underworld. Slowly, they've stopped talking about what they've lost, and they've forgotten that there was a way to get to the surface.
Yet time passes by as their population grows and their beliefs and opinions of them differ. However, because of how many hundreds of years have already passed by, they forget that there was a path to slink off at that place.
Slowly, they were lacking food, and the place was slowly collapsing because of the climate change from above.
However, whether you liked it or not, there would always be people who were born voracious and greedy. Because of those kinds of people, the place that was once called peaceful now turns into a warzone like the place that they elude back to the surface.
How could they bring back peace? How could they avoid war again?
As their population rises, their views and perspectives on them diverge. They forget there was a passage to slink off at that location since hundreds of years have passed.
They were gradually running out of food, and the area was gradually disintegrating due to climate change from above.
