Miryum was a doctor and staff at Walden Freeman Army Hospital.
Miryum and her staff was approached by Dana Scully who brought Mary Hendershot with her, soon to deliver a baby who she believed was not her own and not even human. She prepared Miryum for delivery. She also took an ultrasound on Scully on her request and assured her it looked normal. She then did another procedure and left the room. Scully had then seen a label on the tape of another woman and was quickly convinced they were being deceived. Scully escaped while Miryum quickly alerted security. (TXF: "Per Manum")
