Ecology

Deep One is a sentient species with its own culture, settlements, and political structure. It is most often found in underwater regions. It is medium-sized, which shapes how it hunts, hides, or fights.

Behaviour

Deep One is driven by culture, faction, and personal motive; can be reasoned with, bribed, or betrayed. Its Chaotic Evil alignment shapes how it engages with the world — predictable in tendency, even when unpredictable in detail. It is intelligent enough to plan, scheme, or remember.

Origin

Deep One is introduced in Kobold Press's Tome of Beasts 1 (2016). Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
