Ecology

Mouse 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 urban regions. It is small-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

Mouse King is governed by oaths, bargains, and a sense of beauty alien to mortals. Its 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.

Origin

Mouse King 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.
