Editing Myst: The Book of Ti'ana (section)

===Part Seven: Last Days===
Unknown to the Council, Veovis never entered the Prison Age. A'gaeris again had provided him with a means of escape. Together they bring about the final collapse of D'ni civilization through a biological attack. They infect most of the ages written by the D'ni, killing perhaps all the D'ni citizens. Aitrus brings his family safely to Gemedet, but realizing the intentions of A'gaeris and Veovis, returns to D'ni to escort Anna and Gehn through the tunnels to earth's surface. Veovis is killed by a treacherous A'gaeris. A'gaeris captures Anna and Gehn; knowing himself to be mortally ill, Aitrus cleverly sets a trap for A'gaeris resulting in both their deaths.
