Fantastic project, I am not worthy!
On topic : I've been reading some Tolkien lore, and some books about Middle Earth, illustrated by various artists, and I came by "the atlas of Middle-Earth" by Karen Wynn Fonstad, a cartographer with a master's degree and so on. She has done quite a bit of impressive work about Tolkien's world, and I was just wondering if this was among the lore taken into consideration in this project.
Now I am looking at a detailed map of Thranduil's Caverns, flip back a few pages there's a drawing of the The Prancing Pony, another flip forward show a detailed drawing of the Tower of Cirith Ungol. Other places described detailed includes :
the Spider's Rind ( with attercop, remember?)
Lothlorien
The White Tower (itself, not just Minas Tirith)
The Morannon
Lonely Mountain
Lake Town
Beorn's Wide Wooden Halls
and many more, MANY more.
Anyway I'm sure this thing will make me wet my pants, thanks to Daerk and his team!
