Game of Thrones may be ending in 2019, but we could soon have a prequel series to look forward to. Deadline reported Friday that HBO has ordered a prequel show pilot from writer Jane Goldman in collaboration with A Song of Ice and Fire scribe George R.R. Martin.

Don't hold your breath for any familiar characters to appear. The prequel will be set thousands of years before the events of Game of Thrones.
