Ecology

Oaken Sentinel is a flora given will and motion, often a guardian of specific groves or a corruption of an existing tree species. It is most often found in forest regions. It is huge-sized, which shapes how it hunts, hides, or fights.

Behaviour

Oaken Sentinel is slow but inexorable, defending its grove or pursuing a hidden purpose only its kind understand. Its alignment varies by individual or is irrelevant — it acts on instinct, drive, or whoever commands it. It is largely instinct-driven; complex strategy is the work of whoever (or whatever) commands it.

Origin

Oaken Sentinel is introduced in Kobold Press's Tome of Beasts 3 (2022). Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
