Foundation: The Mathematician's Ghost

 "It's just that you always leave me..."

Time passes. We see nothing of Gaal (though she narrates; we shall see her again)  or Raych, as decades have passed and a tenuous settement is set up on Terminus. Hari Seldon, statues aside, is not in this episode, yet his legend permeates everything.

We begin, though, with a fascinating examination of Cleons I through to XIV, all with Eto Demerzel and all very much knowing what she is. We see the life cycle of an emperor, from an embryo grown in a vat to the final "ascension", a kind of dignified execution. For each birth, there must be a ritualised death. Only three brothers may exist at once.

It's just as fasciniating to see Terminus, its frontier existence with its Encyclopaedia as contrast.There is a mysterious artifact, the Vault, which only Salvor Hardin can approach. Wde get to know Salvor, her active, thinking mind in a society of ossified fatalists who see no need to act as the Seldon Plan will save them. So when Anacreon seems to be invading they know not what to do.

There are so many nice little touches, too... Salvor's lover is pushing seventy but seems half that age from spending decades on "cryo-ships". No one on Terminus now understands the mathematics of Psychohistory; they're acting blind. And it's fascinating to see the dynamic between Salvor and her parents. This is absolutely brilliant.
