The Babylon Project

Ms. Donne was a Psi Corps agent attached to the Interplanetary Expeditions ship Icarus and its mission to Z'ha'dum in 2256.

She was assigned to the IPX expedition to monitor the actions of the archaeologists around technology that had already proven dangerous to telepaths, and - secretly - to smuggle samples of that technology for Psi Corps to study. Shortly after the journey begins, she is revealed to be a murderer and a fetishist, keeping "souveniers" of those she had killed, including her own father.

After several members of the team are captured by the ' Egg', she kills Dr. Chang. She is killed in a cave-in after attempting to escape an underground Shadows facility, not before killing Dr. Churlstein, who had willingly become an emmisary of the Shadows.[1][2]
