On a lost world, far removed from Earth, a group of humans struggle to survive.

Two thousand years after their ancestors lost control of a hidden genetics research facility, the descendants of mankind have been reduced to a tribe of two hundred survivors. They fight, kill, and die in an endless cycle, all in the hope that things will get better.

Lucia is one of these colonists and the daughter of the tribe’s leader, the Director. Together with several other candidates, she must soon undergo a trial to decide her father’s replacement. The winner will shape the future of the entire colony.

But the trial is dangerous, meant to test each candidate’s wits and strengths to see who is truly worthy. To claim victory, Lucia will need to venture out into the tunnels near the city to search for lost artifacts known as Cores–small but powerful devices capable of harnessing endless energy.

But there are monsters here, waiting in the dark, and they are always hungry. Beware the Boneclaw, Lucia’s father use to tell her, for it lives only to kill and to feed.

Lucia must do whatever it takes, learn as much as she can, and fight with every ounce of strength if she hopes to make it through the day.

Forget winning the trial. The real challenge is staying alive.
