Book of the New Sun X Adventure Time

I am a huge fan of Gene Wolfe's Book of the New Sun, and also Pendleton Wards Adventure Time, when I was reading the Adventure Time comic I saw a panel in which underneath the surface of the Land of OOH is the world we know, with cars and trains and buildings and stuff.
this got me thinking about how Urth is the Earth we know but millions of years in to the future, maybe Adventure Times Land of OOH is the same as Severian's Urth...

This is where this piece of art came from...

Sorry for the long explanation, anyway above in order from left to right are, Severian, Triskele, Dorcas, Agia, Agilus, Jolenta and the big guy is Baldanders!

Hope you like it, and I hope you see my insane reasoning for this!

A thousand ages in thy sight
Are like an evening gone;
Short as the watch that ends the night
Before the rising sun.
