Lt. Erin Donnelly is a Security Officer on board the Federation starship USS Enterprise, NCC 1701.

Early HistoryEdit

Erin was born on Tarsus IV where her father was stationed. Her childhood was pleasant and uneventful. She spent her time at school, playing and once she became a teenager baby sitting her father's co-workers the Riley's baby Kevin.

The year 2246 changed all that for Erin and everyone of the 8000 colonist on Tarsus IV. An Alien fungus contaminated the colonies food stores rendering most of them inedible and threatening the colony with starvations. Worse still a major ion storm in the sector was delaying Starfleet relief efforts to the stricken colony.

A member of the colony government, named Kodos, used the crisis to seize power and remove the appointed Governor from power and taking the position for himself.

Massacre at Tarsus IVEdit

Having taken control of the government and playing upon the fears of the populace Kodos took desperate and horrific measures to ensure the survival of those he saw as the most fit in the colony. Using his own theories of Eugenics Kodos systematically choose 4000 colonist to be executed. When there was resistance those who resisted, such as Erin's father were killed as well.

Erin, took the baby Kevin from the Riley's moments before Kodos death squad arrived and hid in abandoned building, moving only when she was forced to in order to avoid the death squads.

History might very well be different if Starfleet personal had not braved the Ion storms at great risk to themselves and their ships and brought relief to the colony sooner then Kodos expected. Never the less over half the colonist had been murdered systematically and ruthlessly. All that was left of Kodos was a burnt body, many people Erin among them believe the dictator escaped Taurus IV. Erin and eight other survivors, all of them teenagers at the time of the massacre, are the only living beings to have seen the face of the man known as Kodos the Executioner.

Erin was placed in the care of Starfleet personal until she was old enough to attend the Academy, training in investigation and combat disciplines in order to be come a security officer. She was posted to the Enterprise when it was sent as part of the task force to Vulcan and injured during Nero's initial attack on the vessel.


Lt. Donnelly is all things considered a well adjusted and dedicated Starfleet officer. The tragedy she experienced on Taurus IV has caused her to become truly dedicated to seeing justice done and protecting those weaker then herself. She is unwavering in her pursuit of those she feels have violated the Federation's laws, she will more often then not presume guilt until she has proof of innocence rather then the reverse. Like many survivors of a tragedy the Lieutenant continues to struggle with survivors guilt. Likewise her feeling of 'playing with house money' in regards to her continued survival leads her to make often reckless decision and risk taking.

Lt. Donnelly maintains a close relationship with a number of other survivors of Taurus IV including Dr.Thomas Leighton and Kevin Riley. Lt. Donnelly is convinced that Kodo's is still alive and at large with in Federation space.
