The show is known for its use of supernatural elements, in particular White Walkers and their army of zombies known as "wights".
But it is unlikely that Tywin will be coming back as a reanimated corpse.
Instead there have been suggestions that next year Game of Thrones will feature flashbacks to Cersei's childhood, which could well include a more youthful version of Tywin.
The series is based on George RR Martin's A Song of Ice and Fire novels.
In the fourth book, A Feast for Crows, readers are given a glimpse into the queen's past and a terrible prophecy from the witch Maggy the Frog.
The new season of the show will be adapted from A Feast for Crows and A Dance with Dragons and will features a whole host of new characters.
However, Bran Stark and Hodor will not be on the show next year.
Filming on the fifth season of Game of Thrones is underway and will broadcast in 2015.
