When I got it from there, I just thought "Good joke, and how nice of you to reference the 'flute quest' of MM6" and threw it away! Hopefully I'll still find it on the floor of the Merchant House in Ravenshore where I threw it away... (Fortunately I haven't thrown it into the water as I usually do with things I deem useless. I guess that it was labeled as a quest item and I was thinking "what if it was good for something after all".)

And thank you for explaining who Lord Brinne was. I don't think I found Zedd standing guard in the tomb (but then I don't remember finding Bones and Flame there either). Flamestryke is a name that is definitely familiar to me, though I was never able to "meet" her (I think I've been visiting these Taverns only for the last 10 years, so roughly from 2012). If nothing else, her MM7 and MM8 websites have been quite helpful when I needed to look up or check some things.

I managed to find some of those "easter eggs", but I guess I got only a small portion of them. I was able to obtain an artifact from a Tree in Ravenshore and another from the back of the Ogre Fortress in Alvar, though. And the Tree in Ravenshore that will quaff your potions and return empty bottles (and it didn't occur to me the first time I used it! I thought "oh, how generous it is of this tree to give me so many empty bottles!" It dawned on me only after I found all of my potions gone — good luck they weren't anything special.)
