Myrt Cary

Myrt Cary is a side character in Origin Stories mentioned in Killerjoy. He is a Rover from Sepperlin that went missing before the start of Killerjoy when he and the Haiguard Arren Argent were sent by Gentina Mildren on a mission south of the Spine. Their goal was the mysterious Maker's Grove, whatever that is.

Of the Rovers sent to accompany Argent, Cary is the last surviving member. Possibly. Neither body was recovered unlike the other Rovers who went with them, but there was no reason to assume they might still be alive. The search for both of them was called off.
