As one fantasy epic ends on HBO, another is set to begin.

"Game of Thrones" concludes this Sunday after eight seasons, dozens of deaths, countless theories, many memes, and even a petition to re-do the final season. But in its wake comes "His Dark Materials," HBO and BBC's big-budget adaptation of Philip Pullman’s fantasy novels.

The story takes place in an alternate universe where human souls take the form of animal companions called daemons. Lyra (Dafne Keen) and her daemon Pantalaimon, live at Jordan College in Oxford. But she gets caught up in a nefarious plot to steal children and the mystery of a phenomenon called Dust.

There have been attempts to adapt Pullman's work before; you may recollect the 2007 "Golden Compass" film starring Nicole Kidman (or maybe, you wish to forget).

The new series also stars James McAvoy as Lord Asriel, Ruth Wilson as the mysterious Ms. Coulter, Clarke Peters as the Master, and Lin-Manuel Miranda as aeronaut Lee Scoresby.

"His Dark Materials" is slated to premiere later this year on HBO.
