At the end of the Cardassian occupation Yevir was in his early forties, his family, bar an aunt he didn't know, were dead. He worked for the Bajoran Militia on Deep Space 9 as an administrator, helping to relocate the thousands of Bajoran families and individuals returning home. Despite the gratification he never really enjoyed his job and was lonely. He attended weekly services but did not really understand the Prophets. Looking back on that time in his life, Yevir remembered his life then "as gray as the uniform I wore."
Yevir's life changed in 2373 after a chance encounter with the Emissary, Benjamin Sisko. At the time Sisko had been granted visions by the prophets, and told Yevir, "You don't belong here. Go home". Yevir took this to be a sign from the Prophets, and immediately resigned his commission in the militia. Returning to Bajor, Yevir devoted his life to serving his gods. His rigidly orthodox views helped him make many allies in the Vedek Assembly, and he rose to the rank of Vedek within two years.
By 2376, he had risen to be one of the most powerful figures in the Assembly and in April of that month was one of seven Vedek's to attend a secret meeting called to discuss the recently discovered Ohalu Prophecies which the Assembly considered heretical. Yevir brought order to the meeting and proposed he return to Deep Space 9 where they had been hidden by their discoverer Prylar Istani Reyla and attempt to keep them under wraps.
His failed attempt to suppress the prophecies made him responsible for the death of Istani. Shocked by the Vedek's actions, Kira Nerys uploaded the prophecies onto the Bajoran comnet, making them public. In retaliation Yevir attainted her. (DS9 - Avatar novels: Book One, Book Two)
Later that year, Yevir persuaded Gul Macet to take him to Cardassia where he set about creating ties with the Oralian Way in hope of creating peace between Cardassia and Bajor through shared spirituality. Whilst on Cardassia, with the aid of Elim Garak, he recovered the final four missing Bajoran Orbs from a wrecked Obsidian Order storage facility. (DS9 - Mission Gamma novel: Lesser Evil)
Several months later, Yevir was on Cardassia once again visiting Andak to view the Andak Project going on there. He later successfully negotiated with Nyra Maleren, a young girl who planned to detonate a bomb concealed on her person on behalf of the True Way.
