wow. Into the lion's den. We'll have to think quick. the best lies are ones with a fragment of the truth mixed in. [a truth that's told with bad intent beats all the lies you can invent]. Suggestion for next time, as I may not be here for it:
"I have been a bit preoccupied (tap the bandages on our face, telling the cover story if necessary), but I have little to report. The symbols are of no civilized language I can find. I will need more time to go through the archives and compare our texts of ancient languages, in order to build a translation. Also, I would ask your permission to bring the relic to a jeweler or silversmith, to identify what grade of metal it was made from, and where such metals or alloys can be found. I know little of metallurgy, and would seek expert advice. This could also help us identify the relic's age. Are there any more notes or journals of findings taken from where the relic was found?"
