"We met another member of the undead in Kheneb-Ptra-urush." Ludo explained cautiously. "She told us about the book in the first place. I mean, originally we wanted it to clear out the undead in Kheneb and loot it more properly. She was one of the priestesses from the civilisation that originally killed Nahorek, and then she accidentally made herself and her army immortal by trying to use the book to defend against the Orks. There's nobody who knows more about it than her... but she's sealed inside Kheneb-Ptra-Urush and the last time we were there, we stole a lot of gold and they tried to kill us."
