The Chatovarians have the reputation of being the best defense builders. It is their boast that no Psychlo attack has ever broken through in their entire seven-hundred-planet empire. They have even shot down gas drones.

Chatovarians love to work with stone: they have small beam tools, like swords, and they cut stone with splice notches so it hangs together with no mortar. They then anneal the stone and make it join molecularly so it is armor-hard. As a result, the whole grain of the stone comes out in bright, glossy colors.
