Teplan

The Teplan were a humanoid species native to the Gamma Quadrant.

During the 22nd century the Teplan fought against the Dominion and lost. As punishment for their resistance the Dominion infected the population with the incurable Blight. 

Due to the similarities between Humans and Teplans, Jasis initially considered the first Humans she saw to be Teplans but quickly dismissed the idea due them not showing any signs of the Blight.
