Lost Terra

Terra is the third planet in the Sol system and was destroyed in 321 ES by the Terran Warlord Unus Tan using technology purchased from the Jovian Collective. The planet broke into large chunks and they lost most of their gravitational attraction to one another so just floated in the space Terra used to occupy.

The Emperor has forbidden all access to the remnants but some still dared dodge the imperial patrols looking for clues of humanities lost past. A few even chose to live among the ruins to hide from imperial control.
