Who are the main characters in Foundation?
Hari Seldon (Jared Harris): a genius mathematician whose psychohistory portends the downfall of Empire. He contains his work in the “Prime Radiant,” which resembles an ornate paperweight but is powered by what appears to be a mix of quantum physics and sci-fi magic. He dies en route to Terminus—his choice, and not the last time he’ll do something seemingly unhinged to help get his math back on track—but re-enters the story later in the season as two different versions of himself, both digital copies: one on the ship carrying Gaal away from Terminus, which we’ll get into in the next slide, and one contained in the Vault (which turns out to have some very TARDIS-like capabilities).
