Domain Borders

As an archfey's power waxes or wanes, their Domain of Delight can grow or shrink. If their domain grows big enough to abut or overlap another archfey's domain, a territorial dispute can arise. Until this dispute is resolved, other Fey denizens of the overlapping domains must defer to both rulers.

Such disputes rarely last long; in the end, one archfey is given sufficient incentive to move elsewhere, or the two archfey learn to live with each other (and other denizens of the region must answer to both).

An archfey whose Domain of Delight doesn't overlap with another archfey's domain can surround their domain's border with walls of shimmering mist or some other magical effect that hides the domain from view and, if the archfey wishes, prevents creatures from entering or leaving the domain without a key, a guide, a password, the answer to a riddle, the archfey's consent, or magic.
