The space ability of the Yinmen Household... could it be something like a 'space transfer ability' conducted through the Domain of Void?
This is the ability of the Body of Light.
As the basic 'Aether Body', as a defensive ability, it can be regarded as 'Data Avatar Body' eliminating the vital points of oneself and balancing damage through 'Ether Phase Transfer', as an auxiliary ability 'Subspace Folding' and for mobility 'Void Jump'... each ability is quite powerful.
Although some abilities seem to be present in other Bloodlines too, the abilities inherent to the Body of Light are equivalent to the core abilities of other Bloodline True Forms cultivated to near their final forms. This is already powerful to an excessive degree.
However, Ian also understood.
This power is built upon the current Terra civilization with the Sublimation Path at its core.
