Minutes passed without anyone re-entering the room, and Arthur continued to wait in silence, mentally chatting with Lostvayne and Celestia.
Unbeknownst to him, a wave of strange energy had begun to seep into the room, its intensity gradually increasing with each passing second.
It wasn't until the energy intensified significantly that Arthur finally sensed that something was amiss.
The airborne legs of his chair touched down on the floor as he blinked in confusion, glancing around.
'…what's this…?'
Lostvayne, who had been narrating how Lucifer had once gotten his ass beat up by the Progenitor Devil, stopped mid-narration and began scanning the room with cosmic energy.
[Apologies, Master,] the sword spoke, its tone unusually subdued.
[It was so weak that I couldn't sense it, but there's some form of psychic energy seeping into the room.]
'Psychic?'
