Orion in the Dying time is a 1990 science fiction novel by American writer Ben Bova.

As they leave the temple together, he spies a statue of Set initially taking it to be a man wearing a totem mask.

Upon arrival in the forest, Anya tries to contact the rest of the Creators only to discover that her access has been blocked by Set thus trapping them in that era without any help.

They then move deep inside the forest where, they hide and encounter another group of humans, who already live there, led by Kraal.

He almost succeeds but Orion manages to break free of his control and he allows himself to be used by the creators to destroy Sheol the sun of Set's home planet Shaydan.

This sets of a cataclysm wherein the debris of Shaydan then pelts the earth with meteors which wipe out the dinosaurs leaving only mammals.

Set is then thrown into a time stasis where he is left to roast forever in the flames of hell.

The Publishers Weekly critic Sybil Steinberg said, "Bova's prose flows easily, the action is vividly described, and the story is enjoyable, but much of the plot defies credibility, even for this genre.

"[1] Kirkus Reviews criticized the book, stating, "Brainless and often absurd, and, with lots of gore and monsters and gee-whiz folderol, clearly aimed at the more juvenile section of the audience.
