When Fafnir mentioned "insignificant matters", she could actually be talking about something way more serious. Otherwise, she wouldn't need Angor to help her deliver a message.
Of course, Angor couldn't point this out.
"Who is Eldiclaus?"
"His name is not for your feeble kind to speak of lightly, human!" Fafnir bellowed as she used another tornado to send Angor into the air.
Thankfully, there was no subsequent attack, so Angor managed to steady himself by using his flying boots.
"I apologize, Lord Fafnir. I meant to say the Great Eldiclaus."
"… He has been staying at the Everlasting Glacier."
Angor just realized that he heard about this place before. When evading a Baphomet Demon, Sennefer escaped into the Everlasting Glacier and contracted a powerful curse that greatly weakened her strength.
