Vaatrik was a Bajoran chemist who owned the chemist's shop on the Promenade of Terok Nor during the Cardassian Occupation of Bajor. Vaatrik and his wife, Pallra, lived a luxurious life for Bajorans of the time, as they had their own private quarters aboard the station. Their privileges stemmed from Vaatrik's lesser known role, at the time, as a Cardassian collaborator. In 2365, Vaatrik met a Bajoran woman named Kira Nerys shortly after her arrival at Terok Nor. He had Pyrellian ginger tea, and Kira, who enjoyed ginger tea, got to be friends with Vaatrik.
