This is the peninsular region of the southeastern part of Breland. It is surrounded by dramatic coastal cliffs, known as the Butte of Breland. The region is composed of gently rolling hills and a near random scattering of villages and hamlets of negligible size. Pastureland for sheep and some farmland are the main land uses, with some mining near the rockier areas of the cliffs. The rest of the land is a mix of meadow and forest, with most roads being little more than dirt footpaths between villages and homesteads. There is one larger road that leads into the region and eventually ends in the only large town, Oscailt, at the eastern end of the Butte.
Seasonal waves of gales sweep in from the ocean to the east, bringing storms that break upon the cliffs, drenching the region in rain before the remainder of the clouds flow north to settle into the twilight of the Everdusk Mountains. These regular rain invasions keep the region green and lush, and feed the innumerable streams that criss-cross the lowlands. Many of the streams flow and merge heading inland to the west, although some empty into the ocean through the beaches to the south.
Brelanders commonly believe that the Éire Lowlands are closer to the Feywild than other parts of Keretore, and the people living in the region are sure of it. Appeasement, dislike and fascination with fairies is a part of the Éire culture, however no fey communities are known. A few of the villages are rumored to be Half-Elf villages, yet none of the people there are inclined to behave as anything other than human Brelanders.
