After Lydia left Faust, it only took her a few minutes to arrive at the Earth Shield faction.
Despite her entering through the front door, no one saw her at all; it was like an invisible wall blocked people's perception around her.
And this was indeed the case.
What Lydia used was her own creation; she called it the Cloak of Invisibility.

It was no big deal for Lydia, but something humanity would need a couple of years to create.
'Let's see... Where are you, little princess Bella? Prince Lux didn't mention how I should approach her, or if I should keep my identity a secret.'
Lydia's playful smile was back.
