Some puzzles' introtext explicitly mentioned the six dwarves from the movie Time Bandits (Fidgit, Og, Randall, Strutter, Vermin, and Wally). In addition to being part of the spacetime metas, the answers to these puzzles are also used in the secondary treasure ("booty") metas.
Want to solve the booty metas? The combined word list for all dwarf puzzles is included below. The four booty metas appear on the Map of All Space and Time (larger version). Finding them and sorting answer words is part of the puzzle.
