On that page, it recorded the commonly used offerings to the Mother Goddess at that time.
In addition to various wooden ritual utensils and the meat of several local demon beasts, what caught Lister's attention the most was a fruit called Purple Mist Eggplant. It was depicted on that page as a roughly round, blue fruit with scaly skin.
As for why a blue fruit was called purple mist, Lister was temporarily in the dark. What he noticed was... In the past few days, whether it was his own one meal a day or the rations he saw distributed to the lamias, there was almost no appearance of any vegetables.
"Enya, come take a look at this..."
Lister took the book and sat down beside Enya, inviting her to look together.
"This Purple Mist Eggplant that was used as an offering in the past... Do you have any impression of it?"
"Hmm..."
Enya leaned on Lister and looked at the contents of that page, frowning.
