The Thysia was the flagship of the Project Exodus Ark fleet.



The Thysia was intended to be the temporary capital of the new Collective until stable colonies could be established.

While the Ark fleet was passing by Earth, an unknown disaster caused all the arks, including the Thysia, to lose propulsion and power, forcing the Arks to land on Earth. During the Descent, the arms of the Thysia broke off the main hub and the hub mysteriously disappeared, assumed destroyed.

The arms, which carried a majority of the Thysia's crew, crashlanded in northern China and eastern Russia.
