Ecology
River King is a creature of the Feywild, bound to seasonal cycles, oaths, and the strange logic of fey courts. It is most often found in underwater regions. It is medium-sized, which shapes how it hunts, hides, or fights. As a legendary creature, it is rare in the world and likely the only specimen of its kind in the local region.
Behaviour
River King 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
River King is introduced in Kobold Press's Tome of Beasts 1 (2016). 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.
