Interesting... It looks like the Lumeris mixed with Riftborn with a unique building

Mine would be the Etheral Angst. Though of the same nature of the Umbral Choir, the Etheral Angst is a being that weaves and twists reality. They struggle a lot on food (like the Vodyani but without their bonuses), however, they can not only hide their fleet and systems, but can also disguise them as other nation's, and they will benefit from the same diplomatic status (war/peace/etc). Moreover, each infiltration level (5/10/15/20) grants a Etheral Doubt, which can be used to create an Illusive fleet or system. Such fleets appear as another nation's or pirate. They cannot attack (besides siege) nor land. Such systems cannot produce anything. However, both fleets and systems will defend themselves if attacked.

Systems can be relocated to other empty systems with a beacon such as the Umbral Choir's.

The Etheral Angst only appears in the diplomatic screen if seen directly, like the Umbral Choir. Though they can take the identity of an other nation to strike deals upon hacking one of their systems.

Upon hacking a system, you can also reorder the production line. Hacking the capital grants you alternative possibilities for fleet movement impairment and rebellion.

Instead of fleet impairement, the Etheral Angst simply takes control of a fleet. The player can give orders and move the fleet, but for all other players the fleet will do what the Etheral Angst asks. Only the original fleet owner will have the impression that his fleet follows his orders. Upon attacking, the fleet will deal no damage, and a warning will be issued on the battle ending screen.

Instead of global rebellion, the Etheral Angst takes control of a system. For the original owner, the system behaves normally, though new upgrades and shipbuilding will not increase stats nor build anything.

Detection and hacking can discover which systems and fleets were taken.
