What can fans expect from the Game of Thrones prequel show, potentially titled The Long Night? Numerous Game of Thrones spinoffs are in the works, but the first will be overseen by Jane Goldman, with A Song of Ice and Fire author George R.R. Martin being credited as a co-creator.

Created by David Benioff and D.B. Weiss, HBO’s Game of Thrones has aired for eight seasons, from 2011 to 2019. And while Martin felt that the story could continue for a number of years to come, Benioff and Weiss felt it was time to wrap things up. However, that doesn't mean HBO is leaving Westeros behind, as the network hopes to get the Game of Thrones prequel on the air quite soon.
