When I saw the "Camelot"/"Dungeons & Dragons" musical comedy spoof 'Galavant' last January, I thought the mini-series would fit into the dimension of Doofus Toobworld along with. 'When Things Were Rotten' and 'That's my Bush!'
But there was a signpost up ahead.....
So 'Galavant' can stay in the dimension of Earth Prime-Time... but on another planet.
'Game Of Thrones' - at least for the purposes of the Toobworld Dynamic - takes place on the continent of Westeros on the planet Mondas. Mondas is Earth's twin (actually "was") and was established first. It is the planet of the Genesis section of the Bible, created by God with the actual story of Adam & Eve. Earth Prime-Time was constructed much later by the Magratheans as a super-computer.
'Galavant' would take place after the events of 'Game Of Thrones', but long before the creation of the Cybermen who transformed the planet's population. And by that time, Castle Black would still be situated at the Wall since it was mentioned in either the third or fourth episode of 'Galavant'. (This is not to say it was still a viable defense against the Wildings and the White Walkers.....)
And during that time, the world of Galavant must have been visited by Sweet the Demon.
If it seems irreconcilable that 'Galavant' and 'Game Of Thrones' should take place on a planet from 'Doctor Who', remember this:
'Breaking Bad' and 'F Troop' both took place on Earth Prime-Time.....
My thanks to Caeric ArcLight, Cartographer for the Lands of Fiction, for the signpost. His picture came out much better than mine.
