D'Hara was founded as an offshoot of Luria. The current Luria Nova was created as part of the core of Luria. Luria Nova was the whos monarch's were granted the claims of Luria by the Lurian Empire and Pian en Luries before them. D'Hara has no such claim to those.
D'Hara in addition was created specifically by those seeking to oppose Luria and its goals. It was built from traitors to the Lurian crown. Why would they retain claim to the lands of Luria?
So what your saying is that D'hara has no claim to the lands it owns? I am a bit confused tbh.
