Game Of Thrones fans worrying about the inevitable end of the show in 2018 need not despair, as HBO is reportedly planning four spinoffs for the massive hit series.

The Hollywood Reporter shared in an article last Thursday that the spinoffs already have assigned writers currently working on the projects. Series creator, George RR Martin, is also said to be involved. While the projects are currently only in the early stages of development, they are expected to explore different time periods of the Game Of Thrones world.

Previous showrunners and executive producers Dan Weiss and David Benioff are not currently involved in any of the upcoming spinoffs. Instead, the spinoffs will be managed by writers Max Borenstein (Kong: Skull Island, Godzilla), Jane Goldman (Stardust, Kick-Ass), Carly Wray (Mad Men, The Leftovers) and Brian Helgeland (Mystic River, Legend). There currently is no timetable for when the spinoffs will premier, or when more information will be made available to Game Of Thrones fans. HBO is remaining very tight lipped on what characters and stories will be showcased.

Regarding the plot for these upcoming spinoffs, fan speculation is already running rampant on various different fan forums. Of the speculation, the hopes for the plot include a prequel story regarding the famed "Robert's Rebellion" era that saw the end of the Targaryen dynasty. Other such theories include "Aegon's Conquest," "The Doom of Valyria" and backstories for certain beloved characters.

Game of Thrones returns to HBO this July for its seventh season. Unlike past seasons, the upcoming season will only have seven episodes. Season eight will be the show's finale. As exciting as it was for HBO to make this announcement, fans are still eager for the final two books in the series from Martin. The last book, A Dance With Dragons was released in 2011, and fans are still waiting for more news regarding the final two books The Winds Of Winter and A Dream of Spring.
