Myst: The Book of Ti'ana
The Book of Ti'ana is the second novel of the Myst series, but chronologically comes first. Set in the fictional D'ni Universe based on the popular computer game Myst, Book of Ti'ana details the origins of Atrus's family. The first part of the book focuses on life of Atrus' grandfather Aitrus with his parents Kahlis (D'ni: Kahlihs/[Kalis]) and Tasera (D'ni: Tasehrah/[Tæsera]), and then on Aitrus' meeting with Anna, called Ti'ana by the D'ni for pronunciation convenience. The book also covers, unlike The Book of Atrus, the life of a D'ni noble, Aitrus, from his youth up to the point where he marries Ti'ana and has a child, Gehn (Atrus's father). Nearer to the end, what used to be a great friendship between Aitrus and a former classmate (Veovis) eventually causes the destruction of the D'ni Empire.
