Special Traits

  • Extra-Dimensional Book Repository. A small door on the chest of the library automaton opens into an extra-dimensional bookcase. This bookcase functions exactly as a bag of holding except that it can store only written materials such as books, scrolls, tomes, parchment, folders, notebooks, spellbooks, and the like.


The humming of servos, ticking of gears, and petite discharges of steam alert you to the presence of this library’s diminutive custodian.


These small constructs were created to fulfill organizational responsibilities of huge libraries with staffing problems, but some invariably learn enough about the wider world to seek out adventure and new knowledge, rather than tending the items in their care.

Eyes of the Past. While largely constructed with mechanical components, the automatons include a single human eyeball that is mounted at the end of an articulated appendage. The eye is usually donated by one of the institution’s scholars (prescribed in their will) so that they can continue serving the repositories of knowledge that were their life’s work.

Telekinetic. While the automatons have no arms, they can move and manipulate written materials telekinetically. Powered by keen analytical engines, the library automaton tirelessly pores through tomes, translates ancient texts, catalogs the institution’s volumes, fetches texts for visitors, and occasionally rids the vast halls of uninvited pests.

Sought by Wizards. Wizards have discovered that these clockwork bureaucrats make particularly effective caretakers for their spellbooks and scrolls while on adventure.

Library Automaton Familiar

If the GM allows it, the library automaton can serve as a familiar for a non-chaotic spellcaster. All the standard rules regarding familiars apply to the library automaton.
