The six issues covered the British Isles, Continental Europe, the Americas, Africa and the Middle East, Asia and the Australias, and the Polar Regions.
All of the information from it was drawn from pre-existing literary sources (such as Shakespearean plays or the Cthulhu Mythos).
The travel reports, mostly compiled from log entries by Mina Murray, Prospero and Captain Nemo (and occasionally quote from them, including Prospero's log written entirely in iambic pentameter), scan over every part of the world in several chapters.
Buried in the exhausting prose are various hints at portions of the story not covered by the graphic novel portion of the volume, such as the adventures of earlier leagues, Murray's correspondence with Sherlock Holmes, Murray and Allan Quatermain's search for the fountain of youth known as the "Pool of Fire and Life" or "the Fire of Life", and their investigation of H. P. Lovecraft-style phenomena and parallel universes for the British government.
The narrator is at times intentionally ignorant, obfuscating literary references and plot points so that they serve as easter eggs.
