The Casciron were a humanoid species located in the Delta Quadrant. They were tall and imposing, with deep gray, glossy skin that was reminiscent of a shark. The way they showed greeting was to cross their arms over their chests, with the left wrist clasped beneath the right hand. The gesture was meant to show that the large, venomous stingers extending from their left wrists were being withheld from use. They believed that removing them would be an act of mutilation that offends the Allfather, a possible deity. By Casciron standards, being mutilated and experimented on was worse than being killed outright. At least one individual named Danros claimed that his species did not deceive, and even though they lost their world, they still had their pride.
