George R. R. Martin is open to aGame of Thronesspin-off.

This has been one of them.

There are eight million stories in Westeros as well … and even more in Essos and the lands beyond.

A whole world full of stories, waiting to be told… if indeed HBO is interested.

A prequel set during Roberts Rebellion, perhaps?

Or a sequel set after the events in the current show?

All this remains conjecture at this point, however.
