The Lowlands

Vast. Unclaimed. Untamed. The Lowland Plains are one of the last great frontiers of Regalia, a massive stretch of wilderness that has resisted conquest, civilization, and even cartography. Nobles call it opportunity. Scholars call it a mystery. Most, however, call it danger incarnate.
  Spanning miles upon miles of rolling grasslands, ancient steppe, and parched desert flats, the Lowlands appear deceptively tranquil at first glance. But those who attempt to traverse its open heart often vanish into the silence, their stories left behind in the bones they carry or the whispers that echo back across the plains. Few roads exist, and those that do fade within days. To cross the region on foot can take over a week, and few survive the journey, fewer still return unchanged.

Geography

The Lowlands are cradled in a natural bowl-like formation.
  To the west, the Draconian Mountains rise like jagged sentinels, their sweeping arc forming a protective wall that curves north to south. Sparse, wind-battered forests cling to the mountain’s base, remnants of an older world untouched by time.
  The north is hemmed by the Histcarp River, a wide, deep-cut waterway flanked by thick, untamed forest. Its dense canopy marks the final breath of the continent’s northern civility before it gives way to the open wilds.
  To the east, the Histcarp Gulf provides a natural divide from the kingdom of House Allyrion, its narrow channel separating civilization from chaos by a thread of water and salt-marsh.
  The south holds the most dramatic transition what begins as sunbaked prairie slowly becomes a harsh, arid desert that stretches to the Gulf of the Five Kingdoms, where massive cliffs drop suddenly into crashing waves far below.
