These spoilers are so minor they're almost inconsequential, but I figured I should err on the side of caution.
The module opens up in Katapesh, in (as the mod says) "the famous Farseer tower", where "Venture-Captain Wulessa Yuul" gives players their briefing.
My problem is I cannot find any mention of this supposedly famous tower in any of my sourcebooks. In the Dark Markets sourcebook it is not found once. In fact, the Dark Markets sourcebook lists the Pathfinder Society lodge as meeting in the three-story building of Katapesh's local Explorer's Guild, which most local Pathfinders are members of.
It then goes on to give the Venture Captain's name as Aurora Steelbloom (both in Dark Markets, A Guide to Katapesh p. 41).
I have no problem altering the mod text to reflect the sourcebook, but before I did that I wanted to make sure I was not missing anything. Is the Farseer tower and Venture-Captain Yuul something that was introduced in previous adventures, or in another sourcebook? Or is this just a discrepancy that should be fixed?
Pathfinder Chronicles: Seeker of Secrets, page 10, Katapesh entry: Elsewhere in the city is Farseer Tower, home of Venture-Captain Wulessa Yuul and her retinue of blind servants.
