 After completing Riven — the sequel to the bestselling Myst — in 1997 , developer Rand Miller and his company , Cyan Worlds , began development of what would become Uru : Ages Beyond Myst . Initially , the game was to have been called Myst Online and have been a multiplayer @-@ only title , but game publisher Ubisoft pushed for a single @-@ player dimension . The online component , branding Uru Live , did not ship with Ages Beyond Myst ; in 2004 , Uru Live was suspended entirely . In 2006 , Cyan developed a stand @-@ in for Uru Live , called Until Uru ; this replacement was hosted by players in servers known as " shards " , and did not have content updates or official support .
