Add "objects" subsections for Artifacts and for Relics (invocation
tools). They aren't very detailed but fill a gap.
I did this a while back but couldn't preview the outcome (aside from
the plain text version). I used to be able to execute the command
'open Guidebook.ps' to display it with the Preview program. That
program is still there but Apple has dropped support for Postscript,
presumably to stop paying royalties to Adobe or whoever owns it.
I've used ghostview for this before but encountered unexplained
trouble this time. It eventually worked; I don't know what changed.
I haven't attempted to update the LaTeX version of the Guidebook, in
order to avoid merge issues with the pending Pull Request in case
anyone decides to incorporate that. (I won't; I still don't have
tools to test it.)
