I missed reporting on this previously. Origin historian Pix posted a few scans from the Japanese cluebook for Ultima Underworld, little comics that were used as chapter headers in the text.

You can find the full guide available for download via Pix’s downloads page. He summarizes its content thusly:

This was written by Tetsuo Kanai and published by Locus in 1994. Like all of these Japanese collectibles, there isn’t a whole lot I can say about the content not speaking the language. It appears to be thorough racking up just under 160 pages with loads of close-ups of specific map areas to highlight where to go for various quests but what usually makes the Japanese books fun for those of us who can’t read them is the unique artwork.

The images above don’t seem to bear much relevance to Underworld’s plot or story, but some of them are rather amusing.

You can check out all six images at Pix’s site, and I’ve also mirrored them here on the Origin Gallery.
