Book Bound. Hp max is reduced by 1 every min it is more than 60' from its book. When hp max reaches 0 dies.

Swarm can bind itself to new book by spending a short rest in contact with the new book.
Construct Nature. Doesn't require air food drink or sleep.
Immutable Form. Immune: form-altering spells/effects.
In the Margins. Can spend half its move to enter/exit its book. While inside its book it is indistinguishable from illustrations on a page.
Swarm. Can occupy another creature's space and vice versa; can move through opening large enough for Tiny construct. Can't regain hp or gain temp hp.
