On September 13, 2103, Dahl descends into the Abyss with engineer Alan Waldeck to assist with the evacuation of Tau. In her report, she says that they waited for the Climber to arrive for 140 minutes before they attempted to contact Tau. Dahl decides to walk toward Tau, thinking she will intercept the evacuees.
While travelling to the site she hears screaming on the short-range radio, leading her to discover the body of Field Worker Espinosa, almost cut in two by a large creature. She listens to Espinosa’s colleagues dying over the radio and decides to hurry back to the Climber, leaving the people at Tau to their fate.
Dahl’s second report on the Tau evacuation (labeled “Carth. Notes”), she states that Johan Ross managed to make it back to Tau in order to continue his work at Alpha. To avoid further disturbances Dahl decides to report the evacuation of Tau as a complete failure, hoping that it will stop Theta from attempting another one.
Simon Jarrett finds Dahl's headless body in the dining hall of Omicron, in front of a notebook which contains her voice records right before her head exploded.
