Midweek Moleskine: Dryadriarch (Patreon)

After a thousand years or more, a dryad may fuse with her birth tree and become a "Dryadriarch", a demigoddess of the forest. Dryads look upon her as both a bearer of great wisdom and a well-respected protector. 

Because my favorite kind of monster is "regular monster but older and fucking huge".
