Atrus
In the D'ni fiction of the Myst books and games by Cyan Worlds, Atrus is the last survivor of the D'ni Empire.
Born to Gehn and Leira (Keta), Atrus was only 1/4 D'ni, the other 3/4 Human. This caused him to age slightly slower than humans. Atrus grew up with his grandmother Anna after his father abandoned him at birth, his mother died in childbirth. Under Anna's guidance, Atrus grew into an inquisitive person, with deep respect for live and moral values. Anna also taught him the D'ni language.
Atrus was named after his grandfather Aitrus (their names are spelt the same in D'ni). He is seen as one of the greatest Writers of Ages.
When Gehn returned to claim his son, Atrus came with him to the ruins of D'ni, where his father taught him the Art of Writing Books: Links to other worlds. Unlike his father, Atrus did not believe the fact he could Write made him a God, and he rebelled against his father. As punishment he was trapped on the island of K'Veer in D'ni, with only a Link to Riven as a way out.
On Riven he met Katran, whom he named Catherine. Catherine was a student of Gehn, and Gehn intended to marry her against her will. Secretly Catherine, together with Anna who had followed her grandson, wrote the Age of Myst, and planned to trap Gehn on Riven.
After trapping Gehn Atrus moved to Myst with Catherine and his grandmother. On Myst his two sons Sirrus and Achernar were born. Atrus was much later trapped on K'Veer in D'ni, while Catherine was lost in Riven.
In the game Myst, the Player meets Atrus near the end, after having read his journals and notes throughout the game.
In the game Riven, the Player again meets Atrus, who now enlists his aid to free Catherine and again trap Gehn.
After this Atrus and Catherine explored the remnants of D'ni, attempting to rebuild the D'ni civilization: a project which ended after Atrus realized that this would lead the D'ni to repeat their old mistakes. Instead he wrote a new Age for the D'ni.
In Myst 3, the Player again meets Atrus and Catherine, who now have a daughter Yeesha.
In the D'ni canon, Atrus died some time after the Myst games, but before Uru: Ages Beyond Myst, which takes place in the present day. Much of the gameplay of Uru revolves around explorers from 'the Surface' (Earth) continuing Atrus' work.
