Game of Thrones will come to an end on HBO after its eighth season, but Thrones fans needn't start getting withdrawal symptoms just yet as the cable network is already making plans for a possible prequel series.

"It’s such a big property we would be foolish not to explore it, but it’s a pretty high bar,” HBO programming president Casey Bloys told Entertainment Weekly. "We’ll take some shots at it."

However, Bloys says HBO won't churn out a new prequel series just because it can.

"I’m not going to do it just to do it. It has to feel very special," he explained. "I would rather have no sequel and leave it as-is then have something we rushed out.”

Bloys said that the history of Westeros gives writers plenty to work with and flesh into a new series, but adds he doesn't "feel any pressure that we have to have something.”

Game of Thrones season 7 is set to premier in the summer for a seven episode run, with the final eighth season to follow, likely in 2018.
