[QUESTIONS and ANSWERS] Walkthroughs for the Heroes 3: RoE, AB, and SoD campaigns.

I need help with screenshots; I can't find the following artifacts while playing the 5th campaign in *The Shadow of Death*. If, in the case of the 12 griffins, I figured out what to do (I waited a month until they appeared on the map, and one group agreed to join me), then the sword is missing from the map, or I simply don't know where to look for it (I found the Shield of the Titan and successfully turned it in, receiving 13 defense for my hero). I would be grateful for any advice!
