The Shadow Mirror acted with the same phenomenon as the Territorial Space, but there were differences which were laid bare for those who were keen enough to realise.
And amongst those differences, a key factor lay in place– Control.
Territorial Spaces were so– the larger the size of the Space, the more control that slips out of the Caster's Psychic, which inevitably leads to the collapse if left to a single caster.
The Shadow Mirror existed as a plain on its own.
A separate domain crafted from Occult and Magic Logic, but without its limits.
Cressida had full control of it.
Its properties, exits, entries, nature and elements.
She controlled everything with a snap of her finger.
How such an artefact was created, and engineered so it functions the way it does, was a mystery to most– and even the Matriarch of the Household who produced it.
But none of that mattered, right now.
