This wasn't the Royal Castle, a fact Bella made clear by showing Lith the different walls and carpet around the castle.
"Why are you here then?"
Bella smiled. "Shouldn't His Highness know?"
"I should?" Lith wondered.
"Yes. Didn't His Highness promise Lady Lucifer a maid for her?" Bella asked.
"Ah…" Lith understood. "But, wait. I never said she gets to choose. Why are you here then?"
"Lady Lucifer did not choose. It was that I was the only one free who could join her," Bella said.
Lith rubbed his chin and asked, "Were there no lower level maids available?"
"There were," Bella said, as a matter of fact. "But they wouldn't be able to serve properly. His Highness should know that the dealings she has are of a much higher level than normal. If a low level maid were to accompany, she may hinder her or get herself killed. The probability of the latter happening is almost nil, but still, why take an unnecessary risk?"
