Rand Miller is one of the two creators of Cyan Worlds along with his brother Robyn Miller. He is now CEO. Together with Robyn, he created not only Myst and Riven, but also earlier games Cosmic Osmo and The Manhole. In the video games, Rand Miller originated the roles of Achenar and Atrus. Although Achenar has been recast, he continues to play Atrus (though he has expressed in an interview with Youtuber "My Life In Gaming" that he had a strong dislike for playing the role during the production of Riven, Exile, and Revelation due to his discomfort of the environment within the studios. In the first Myst game, though, he stated that he felt it was fun playing Achenar and Atrus's roles alongside his brother Robyn). In addition, he has worked with David Wingrove to write the novel series.
