Glessin joined the Guard where he trained to be a medic. While doing so, he met another Cardassian who was a medic on Terok Nor.
Glessin had finished his mandatory tour in the Guard by the 2370s and began to study biology under a person who was actually a member of the Obsidian Order. The teacher recommended him to the Order, who assigned him to the Keldon class starship Danasket. The ship was stationed in the Orias system for the joint Obsidian Order/Tal Shiar attack on the Founders' homeworld in 2371.
After the Cardassian and Romulans believed they had eliminated the Founders, the Dominion fleet secretly stationed there began their attack. A young soldier forced Glessin into an escape pod, which managed to avoid detection by the Jem'Hadar. (DS9 novel: Rising Son)
Six days after the Battle of the Omarion Nebula, Glessin was rescued by a Merdosian salvage vessel. He spent a year aboard their ship, until he met Zin Dezavrim, the Captain of the Even Odds, in 2372. Dez offered him the position of medic aboard the ship, which Glessin accepted.
