Veovis' plague

Veovis and A'gaeris developed the plague which caused the fall of D'ni. It took the form of a poisonous cloud which was spread through the cavern by the ventilation system. Anyone in contact with it died, and Veovis and A'gaeris spread it further by linking infected corpses to Ages with D'ni refugees. Aitrus caught this plague and accidentally brought it to Gemedet, killing Tasera and the servants.
