Amelie's Growth and Moon thralls invasion

After some time of talking, a notification entered their ears as they reflexively shut their words, and read the holographic screen in front of them.

[Constellation 'Mistress of Twilight', says one of her subordinates is coming in a minute.] 

[Constellation 'Mistress of Twilight' activated the Skill: Eternal Barrier (God)]

[You will be protected against any 'pressure']

Derek, who saw the notification felt a sense of nostalgia as he read the messages and thought. 

'Was this the barrier the Mistress used on me when "she" materialized in front of him?' He let out a self-deprecating sigh as the feeling of wanting such skill surged within him.

...

As considered a 'Party' under System's rules, Amelie Rose also saw the System messages behind the 'notifications', she silently thought of various questions in her mind.

'Constellation [Mistress of Twilight]?' 

'Eternal Barrier?'

'Is she the Mistress that Lumiere spoke of?'
