Rollbugs

Rollbugs are curious and small invertebrates that show strangely high intellect and capacity for learning well beyond most similar arthopods. They are segmented creatures anywhere from 5 - 30 cm long and include a wide variety of species and variants. Their primary noticeable quirk and their namesake, is their habit for wrapping around objects - particularly humanoid-made ones. Their upper shell is incredibly strong and underside muscles stronger than most predators can pry. This comes at the cost of their undersides being incredibly weak. Therefore, as a defensive mechanism, they will wrap themselves around small cylindrical object, a behavior that also seems to comfort the Rollbug. Rollbugs favor objects based on their size, but particularly enjoy handles or hafts of humanoid weapons, posts, and scrolls.

Their unique preference for scrolls is what led to their intellect being examined in further detail. A Terr'ainan biologist ran several studies, finding that Rollbugs had adapted to live with humanoids, and intrinsically understood the protection they could provide. Rollbugs gain benefit from the way humanoids protect their precious items such as scrolls from pests and predators, but also understood that direct contact with them was usually unfavorable. However, by interacting more favorably with Rollbugs, the Terr'ainan biologist was able to teach Rollbugs to cooperate and coexist, defending scrolls from smaller pests and detaching when required. Several decades later, many librarians utilize Rollbugs - and selective breeding in order to create Rollbugs that can guard or effectively lock a scroll has even had success in some areas.
