Cheslile

The Cheslile are an enigmatic species of gas giant dwellers that reside in the Perseus Arm. They had limited contact with the Covenant, with the most recent intelligence suggesting that they were in a fairly settled, sedentary state with few territorial expansions. Some evidence available to the Covenant suggests that the Cheslile may in fact be a tributary species to an as-of-yet unknown polity, though this has not been substantiated as the Cheslile are notoriously reluctant to deal with outsiders. Covenant records imply they are roughly the Covenant's technological peers, which coupled with their distance from the Holy Ecumene made their conversion non-feasible.
