No, You two aren’t the only ones.

My first thought was 8 pages, which gives me 16 total, suitable for a cover and a back cover. With plenty of room for some maps and tables.

So, yeah, I’d love some clarification on this too.

In the previous game jam, the cover was part of your page limit, because the cover can be used to add additional content which would put you over the 8 page limit.  The text on the jam says 8 pages or less. Must include your inspiration statement, so legal should be presumed necessary there as well.  Keeping in mind that the adventure The Hideous Halls of Mugdublub in Cursed Scrolls 1 clocked in at 16 pages A5 (or 8 pages A4) and is a 33-room dungeon, you should be able to include a cover & legal in the 8 page limit. 

This is from the official Arcane Library Discord channel for this game jam. It doesn’t matter if it’s a cover page or not, it’s part of the 8 total pages.
