Once Upon a Time in the North, a fantasy novella by Philip Pullman functions as a prequel to Pullman's His Dark Materials trilogy. The premise of the story involves the meeting of Iorek Byrnison and Lee Scoresby — an incident originally expected to appear in The Book of Dust:

When we see them for the first time with Lyra, Lee is not that old; he's fifty, sixty, something like that, so they know each other for a long time.
