The Tarsilja Hollow is a spatial conduit perforating the moon Tarsilja. A relic of the Lost Ages, it operates akin to other Rifts, conveying those who pass through across the expansive cosmos in but a moment.
One of the more storied uses occurred in 734. Persecuted Eenkai intellectuals from the world of Throndar utilized the Hollow of Tarsilja in their journey to a new homeworld. Passing through in their massive Eenkai Void Pods, they departed the Asteraoth System for the adjacent Quara'tun system and its world of Geb's Rain.
The Hollow of Tarsilja is not a conventional rift. Some postulate it to be archaic technology remnants from the Lost Ages.
