A story that upon reading it, sticks in the memory as being longer than it actually was.
It’s a half dozen pages long, but has a big compass, starting with an intelligence whose “name was a multi-dimensional index that spanned the region in spacetime occupied by his countless avatars”. Into his purview comes a generation starship, long, long into it’s voyage, it’s AI somewhat compromised. And on the starship the humans have reverted to an altogether more primeval existence.
Enough invention to fit a much longer story, and worth the read.
