Top Ballista

Anyone have the old Creature Crucible: Top Ballista for OD&D? I saw
it is available at SVGames on the ESD page, and thought it might be a
great resource for those designing tinker gnome Spelljamming
colonies. The description says the book describes a flying gnome
city! And the cover has a gnomish biplane about to get eaten by a
dargon.

Anyway, just looking for some feedback on it!

certainly mean fighting. You won't rescue Lotho, or the Shire, just
by being shocked and sad, my dear Frodo."
