“In a hole in the ground there lived a hobbit. Not a nasty, dirty, wet hole, filled with the ends of worms and an oozy smell, nor yet a dry, bare, sandy hole with nothing in it to sit down on or to eat: it was a hobbit-hole, and that means comfort.”
― J.R.R. Tolkien, The Hobbit, or There and Back Again

“Elodin proved a difficult man to find. He had an office in Hollows, but never seemed to use it. When I visited Ledgers and Lists, I discovered he only taught one class: Unlikely Maths.

― Patrick Rothfuss, The Name of the Wind

“She wants fire, and Dorne sent her mud.

― George R.R. Martin, A Dance with Dragons

“Tell me, tutor,' I said. 'Is revenge a science, or an art?”
― Mark Lawrence, Prince of Thorns
