Asterion

The Empty Throne
Once the host of an advanced alien civilization known only as the Asterion Progenitors, Asterion is now a bleak world wracked by endless storms and almost permanent cloud cover.

The disappearance of the progenitors is no mystery to the Jerrys, as the planet only now emerges from millenia of ecological imbalance.

Jerry Homeworld
The Jerrys appeared on this world under mysterious circumstances long ago. Here they found incredible alien technology which likely caused the deaths of many immortals. Interestingly, modern Jerrys acknowledge that the relics contain a staggering amount of safety mechanisms.

Both the Unity Engine and the blueprints for all Jerry space technology originate with the designs of the progenitor race.
