Ecology
Undine is a creature of the Feywild, bound to seasonal cycles, oaths, and the strange logic of fey courts. It is most often found in coastal regions. It is medium-sized, which shapes how it hunts, hides, or fights.
Behaviour
Undine is governed by oaths, bargains, and a sense of beauty alien to mortals. Its Chaotic Neutral 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. Spellcasting expands its repertoire well beyond what its physical stat block alone suggests.
Origin
Undine is introduced in Kobold Press's Creature Codex (2018). Fey trace to the Feywild and the eternal courts of the seasons — the Seelie and Unseelie, or older powers. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
