Private MMORPG game MU Imperio is a highly involved fantasy RPG based on the legendary Continent of MU.
"In the ancient era of the MU Continent, a thousand years of peace are shattered when the ambitious Prince Antonias, misled by the sorceress Lemuria, breaks the Seal of Etramu. This catastrophic mistake releases Kundun, the Demon Lord, who plunges the world into darkness and chaos. As the seal fragments into mystical jewels—now the lifeblood of the continent’s economy and power—the three main kingdoms of Lorencia, Noria, and Arcas must unite their greatest warriors. Players take on the roles of the Dark Knight, Dark Wizard, or Fairy Elf to reclaim the lost lands, master the wings of the heavens, and face the rising tides of evil in a classic quest for survival and glory."
