The civilization of the Thoth is apparently old and ragged, much older than human beings, though his species still remains advanced in terms of intelligence. Vast ruined buildings are all that remains of their cities which evidently once thrived and housed millions (the architecture of the buildings is odd as the bases are small but widen out as they get higher). Much of their technology has since been lost to history as the limited natural resources of Mars were completely depleted long ago. Only a few hundred Thoth remain on the dying world.
