Encounters

 * The Oneshotters first encountered Lady Sessa directly in the city of Phsant, which had been all but abandoned by Surthay at that point. She arrived riding a dracolich (likely animated and controlled by her). She singlehandedly took on the party, nearly disintegrating Bareth, dominating Ailuin's mind, and killing Krystal with a Power Word Kill (a 9th-level spell). Krystal was later resurrected in Veltelar by the Temple of Azuth.
 * Lady Sessa was present in the peace meeting between the Oneshotters and Surthay, revealing herself as the leader of Surthay.
