Daschla is a val'kyr in service to the Dark Lady. She is present for the meeting between Garrosh and Sylvanas, where Sylvanas reveals that the val'kyr have joined the Forsaken. The nearby val'kyr Agatha then resurrects the nearby fallen corpses as Forsaken, much to the disgust of Garrosh and High Warlord Cromush.
Daschla later aids in the resurrection of Lord Godfrey and his lieutenants. When Lord Godfrey betrays and kills Sylvanas, Daschla, Agatha and fellow val'kyr Arthura sacrifice themselves to resurrect the Dark Lady.
