Groznik was a Denobulan man who had a habit of annoying the people near him. As a Denobulan, he had three wives. However, it seems Kessil left him sometime in the early 2150s. Sometime prior to 2149, he did something horrible to upset his wife Vesna. She hadn't forgiven him by 2152 despite the fact that he'd apologized twice, but Feezal felt she'd forgive him after another two years. Between 2149 and 2152, his wife Kessil, who'd lived with him on Denobula for some time, decided to leave him to move in with her third husband, Bogga, on Teerza Prime. (ENT: "Stigma")
