Mothermarket (Sefenlander: Mahexiaxou, "Motherhome") was the capital, and most-populous city of the Kingdom of the Ghost Isles (now the Calm Isles), one of the Seven Sefenlander States of the Empire of the Sefenlands, with a population of 555,550 people (500,000 slaves, 50,000 peasants, 5,000 serfs, 500 "freedmen," and 50 slave masters). The city lies between the Keylmes Kove, and the Witewynd Mountains of Slave Master's Isle. Its ruler is Lord Helmes Nightbright of the House of Nighbright, who rules it from Bammfir Isle's castle seat of the Night House. The city was finded by the Keylmes Klan, an ancient line of chieftains from the Beyerlands. The Ghost Isles, for thousands of years, remained a relatively obscure kingdom of desert islands within the Empire of Sefenlands.
