Cap'n Fentus told me to find Sharai-Saldro's Astrology in Saldro Ancestral tomb. Fentus told me to hurry. Antio Florane, a fellow member of the Guild, got wind of the treasure and trying to get to it before I do.

I've met Antio Florane in the Saldro Ancestral Tomb. He mocked me for being slow, saying that Sharai-Saldro's Astrology was already in his possession.

Antio Florane didn't let me see Sharai-Saldro's Astrology, so I can't be absolutely certain that he indeed has the book. I can either give up and return back to Old Ebonheart or search the tomb to see what I can find.

I asked Antio Florane to show me the book he had found in Saldro Ancestral Tomb. He showed me a copy of the Firmament. Since he's got the wrong book, I should search the tomb and see if I can find the right one.

Cap'n Fentus told me that I shouldn't have given up so easily. The book Antio Florane found in the tomb was not Sharai-Saldro's Astrography. The unhappy Fentus said he'd find someone else to fetch the book for him.

Cap'n Fentus didn't care if I had found Sharai-Saldro's Astrography or not. He was mad at me for killing Antio Florane.
