This was... a rare greeting initiated by Mr. Fool!
Justice Audrey, who had been about to lead everyone in rising to pay their respects, froze, both delighted and puzzled. She instinctively interpreted this change as a sign that Mr. Fool had achieved some long-term goal or encountered something pleasing, allowing his emotions to show. Yet she dared not be certain whether a true god would still display such human qualities.
Fortunately, he showed no further changes at the head of the long table. Audrey, who had already digested most of her Dreamwalker potion, calmed down and led the entire Tarot Club in bowing and greeting him as usual.
The Fool Klein nodded slightly in response, but his gaze remained fixed on Empress Angel, who sat closest to him.
Ever since everyone had appeared in the palace above the gray fog, an additional, denser cloud of gray mist had begun shrouding Angel's seat. Angel herself, under the gray fog's protection, might have found it difficult to notice, but to Klein, the master of the gray fog, it was unmistakable.
Drawing on his past experiences, Klein formed a conjecture about this peculiar phenomenon:
The Grey Fog Space, or what he understood to be Sefirah Castle, had mounted some kind of defensive response against this outsider!
The last time the gray fog had undergone a similar change was after Angel's battle with Abomination Suah. A trace of corruption belonging to the Mother Tree of Desire had remained inside her, and the reaction had only occurred after Klein brought her above the gray fog.
This time, it was most likely related to Angel's advancement to sequence 2 and becoming an angel. Alternatively, her control over another sefrah, the City of Calamity, had strengthened, leaving its aura within her and provoking a response from Sefirah
