"Foundation" The Emperor's Peace(2021) !!LINK!!
Seldon's predictions come to pass, and both he and Gaal are arrested. During his Kangaroo Court, Seldon is unapologetic, insisting that he is no radical but is merely outlining what is essentially a mathematical truth; however, he also insists that if his theories are listened to, then the coming dark ages can be reduced from 13,000 years to a single millennia through the establishing of a "foundation" to preserve knowledge and the story of humanity. When Gaal, sure enough, is given Seldon's equations in the form of a "Prime Radiant" and ordered to discredit them, she realises that he is telling the truth... and bravely supports his theories in public, condemning herself.
