Realm of Shinto
Lucifer, Bariel and Aphrodite just arrived back at Shinto and was about to go inside the Devil's Palace when Tiānkōng ran out to welcome him.
"Greetings master, welcome back from your travels" she bowed her head along with the other servants and after that, she raised her head and brought out a letter and handed it to Lucifer "this letter was delivered by a lesser god from the Greco Realm, said it is from the Primal goddess, Gaia" she said after giving him the letter.
Lucifer took the letter from Tiānkōng "you can go now, I will send for you when I need your assistance" he said and with that, Tiānkōng left them along with the servants "I wonder what made her write to me this early"
"There is only one way to find out, why don't you open it brother?" Said Bariel as he was wondering who this Gaia could be and what is her relationship with his brother.
"You are right, brother" said Lucifer as he opened the letter.
