A little on book spiders

The Great Library of Motometro is so ancient and expansive it has become host to more than librarians and the occasional visitor wandering its aisles. It also maintains a highly specialised array of creatures that have evolved to live among the shelves. The most prominent among them being the Book spider, and its preferred prey, the Paper slug.

The humble book spider begins its life as a tiny, crab-like arachnid; an awkwardly vertical, carapaced critter balancing on stout legs. It's during this time they are most fragile, and at risk of being crushed by the weight of shuffled books, or swept up by the feathery threat of a librarian's duster. Despite occasionally frightening visitors and novice librarians, the spiders are generally encouraged, for they keep down the numbers of the significantly more destructive Paper Slugs.
