FROM: Tassyn
Thank you for your help resolving the Leyton matter. You did the right thing. We can't run the risk of having a Dominion mole right here in Fort Tarsis, and certainly not one married to a Corvus agent.
I wasn't entirely convinced that offering him leniency was the best course. Enemy spies are best dealt with in the most expedient fashion. But in this case, Leyton offered us a direct pipeline back to the Dominion and that was too valuable to pass up. By feeding him the right batch of useful intelligence mixed with disinformation, we can fool his handlers in Stralheim into thinking whatever we want. Nobody ever said spies played fair.
In the meantime, if you're wondering about Nadira, you should put your mind at ease. You did what had to be done. Whether this disrupted their marriage or Leyton's feigned "emotional healing" isn't our concern. It was clearly all an act, anyway. I've reassigned Nadira elsewhere, in a role without access to any classified secrets. I've given her a choice: she can either devote herself to writing supply requisition forms, or she can leave this organization.
Regards,
Tassyn

My dearest.
I cannot wait to come back to Stralheim. The weather here is very hot, and I miss the cool air of the north in my lungs. Each day is a test, one I fear I will fail. Our Monitor is unbending in his will, and the southerners are not as weak as we thought. The only thing that gets me through is thinking of being with you again. You are my light.
Sincerely
Gehert
The Monitor (1)
See Cortex Entry: The Monitor (1) for More Details
A rare Dominion operative who is both a skilled lancer and cypher. He is invaluable to the Dominion's expansion plans. Monitors undergo special training to make them into near-omniscient secret police. Corvus first heard whispers about the Monitors from small bands of refugees fleeing south from Stralheim to Freemark.
