In Curse Of Strahd, Ismark encountered a group of strong adventurers, and he pleaded with them to take Ireena to safety in Vallaki. Ireena refused to leave until Kolyan's body was given a funeral at the Church of Barovia, which the outsiders assisted with. She traveled with the "Pack" of Shakti of the Wildhunt, Ghalwin Forrester, and Jarmo Maulgrave, eventually developing a relationship with the latter through their adventures.
Young and with little experience of foreigners, she was smitten by the intelligent and caring Giantborn, and the two learned how to protect eachother in dangerous situations. Fending off dangerous situations together, they eventually confessed their care, and shared an intimate night at the Blue Water Inn. But this love would prove their undoing; visible as it was, it reached the ears of Strahd von Zarovich.
The Pack would end up on a hunt to restore Saint Lugdana Andral's bones to Saint Andral's Church, ensuring the area was Consecrated and safe for Ireena to stay in. This resulted in an attack of Vampire Spawn in the Vallaki Town Square, where Strahd was summoned; he kidnapped Ireena through magical charm and stole Jarmo's protective Dreamweave Circlet, which turned the goliath to stone. On the back of Beucephalus, Ireena was taken to Castle Ravenloft.
The Pack took Jarmo's body to a hidden alcove in the church, keeping it next to Saint Andral's bones, but would ultimately be unable to save Ireena before their own dissolution.
