The people of Earth have been summoned once again

Scientists document six extinction events in Earth's history, but none of them were as natural as they claimed.

Sylas and his family have been called back to the Browns, a family of billionaire elites with assets reaching into the trillions. He isn't sure what to expect until he touches a floating bronze cube that changes his life.

[Bronze City Stele]

[Time to Activation: 04:13:38]

Unfortunately, there's only one Stele and the Browns have already decided upon their candidates. If Sylas wants to control his own fate, he'll have to enter the Trial.

Now, woefully unprepared, and stuck in a world filled with the extinct creatures of Earth, he'll have to carve out his own opportunity... whether the Browns like it or not.
