Season 1

The wanderer Jeremiah comes to the market community Clairfield, looking to barter for supplies and maybe get a lead on the whereabouts of the Valhalla Sector. The place is run by the beautiful Theo, a woman obsessed with getting her hands on as much knowledge and technology as possible. When her guards discover a well-maintained, fueled car hidden nearby, she's sure the owner can lead her to the jackpot. Pity those who should get in the way.

Jeremiah and Kurdy make their way towards Thunder Mountain, hoping to find whoever Simon was working for.

A somewhat fanciful tale of a guy who grew up after the Big Death believing that some day the super heroes he read about as a kid would come back and fix things...and a tale of a most unusual romance between another of our main characters -- Marcus Alexander, head of what was once the NORAD Thunder Mountain complex -- and a woman whose existence has been kept secret from everyone for years.

Markus' father insisted on going out to be his wife, exposing the base. Quantrell escaped to Valhalla Sector.
