Eather offers to buy your circlet as well for 95% value, but she says that's the most she can do for now, as her discretionary funds are not unlimited.
She also finishes her goblet of wine and addresses your other points, "As for divinations, as I've said many of our efforts to scry or magically gain information on events or persons in Maerimydra have been blocked. It's likely the parties attempting to view you and visit unpleasant dreams upon your persons are doing so while enjoying some similar manner of magical protection. Tesper and I have some experience in these matters and it seems that the advantage usually lies with those who are casting their divinations from a well-protected sanctum, and the disadvantage with adventuring types such as yourselves who are usually on the move and thus unable to consistently remain within a protected area. I can assure you that this 'humble tavern" is well protected but beyond that there's little I can do to keep them from eavesdropping on you when you're off in the Deep Wastes."
"As for more indirect divinations, such as clerics communing with their diety or our mages contacting outer planar sources of information, such methods haven't had much more success for us thusfar. We've only managed to find out that some manner of tragedy has befallen the city of Maerimydra, a civil war or insurrection of sorts, but no more than that. Again, perhaps you might have better luck if you sought information by such means about the drow who evaded you and fled Szith Morcane."
