Panoptant

From publisher blurb:

Serving as keepers of lore and guardians for druid circles throughout the world, panoptants are massive beings made from plant matter and dozens of smaller creatures known as panoptins. Druids create panoptins as living repositories of knowledge, and may assign them specific tasks they go to great lengths to accomplish. When panoptins return to join the others of its kind they create a panoptant, which both serves as the central hub of the circle’s knowledge and as a guardian for the circle’s home.
