"I'VE already sealed a piece of Neoma de Moonasterio's soul with the Eternal Flame."
Yoan bowed politely as a greeting to Serafina– the World itself.
[Sometimes she's called the World Tree, too. But the Cosmic Tree is more famous than her, so people would just often refer to Lady Serafina as the 'World.']
"Thank you, Lady Serafina."
Serafina stopped knitting and looked at him with a disapproving look. "You're expressing your gratitude and yet why do I feel like your disdain? I gave Neoma what both of you had wished for."
"Please don't pretend that you did us for our sake, Lady Serafina," he said indifferently. "After I retrieved Neoma's body from the dark ocean, we realized that the residues of her Lunacy remained a threat even when she was already gone."
It was hard for him to talk about Neoma using the past tense, but he had to continue and act tough in front of everyone.
