Ferro is one of the many ancients that lives in the monastery known as the Retreat in the Veil of Mists. After Gabrielle, Trixie, and Teagan showed them the general area to look, he, Dragomir, Sandu, Isai, Petru, Benedek, and Andor set out to find their lifemates, hope filling them once more.

In Dark Sentinel, Gary aids Andor as a healer. However, with Andor so gravely wounded, he had to try and retrieve him from the Tree of Life. He did this for several risings, but had to eventually call on the aid of Lorraine, Andor's lifemate. He, Gary, and Sandu bound their souls to Andor and Lorraine to protect Lorraine, as she was still human at the time, as she binds her soul to Andor's. However, he has chosen to return to the monastery to seclude himself once more as he believes he could never embrace a modern woman, even one born as a Carpathian and taught their ways. Siv elected to go with him to act as gate keeper. However, this was changed when Ferro heard Elisabeta's muffled cries in the healing soil at Tariq's compound and found out she was his lifemate.
