We join our heroes as they orbit Ashan with the Terraformer army on it's way. They come into contact with the same research team they worked with on Cunniculum Rocks which is currently investigating legends about how the ancient Ashan people created servants from metal and lightning and how those servants rebelled and the Ashan people created a giant Ziggurat to steal back the lightning. They decide this might hold a clue to defending against the terraformers, and the go to help the research team.

Talking to an Ashan tribe, the learn where the Ziggurat might be located, but the area is guarded by a rival tribe. The crew decides to fly into the area with a single tribal to avoid attention from the other tribe. They take a young tribal woman named Kamala to be their guide. They quickly find the crevice that leads to the ziggurat underground. While exploring the caves, the rival tribe comes to investigate. Decatur distracts them by going back with tribals to the village to eat and hunt with them.

The rest of the crew finds the ziggurat underground. It appears to be some sort of EMP broadcast device. To repair it, they need a power source, fix the physical damage, and attach some sort of targeting device. Lemons figures out how to power it by jury-rigging up a device that will focus energy from the ships beams weapon to power it. For the targeting device, they need the probe they recovered from the Binchuran home world. Tali convinces the Binchuran fleet to let them use the probe as the targeting device for the ziggurat.

The Athena rushes out to meet a Binchuran ship with the probe while Lemons fixes up the ziggurat. The Athena manages to secure the probe and escape with the Terraformers hot on their tail. They install the probe and use the ziggurat to destroy the terraformers right before they reach the planet.

As the crew celebrates, Redlen discoveres he has some how accidentally married the tribal woman Kamala.
