Moments after Ezra left the siblings, a portal emerged in front of the establishment, and a lady with a hat garbed in all purple stepped out.
It was Elisa.
Just as Valentine could pinpoint her mother's marks, Elisa could feel the fluctuation of her marks.
A marked set point was a space mage's signature, it would be weirder if they didn't notice an intrusion.
Of course, that didn't mean they could interfere when not nearby-they were simply notified.
Elisa took it a step further. She'd placed a marker on Valentine the day she dropped her off at Arcadia, as a measure of safety.
The marker did not tell the person's condition else Elisa would've appeared at Arcadia before Ezra would have woken up.
Also, Arcadia was a prison at least five centuries old, with only ten inmates ever escaping-Elisa could've never foreseen its destruction nor would she have believed it.
As such Elisas was immediately alerted the moment Valentine stepped out of Arcadia.
