As I haven't seen all the (mostly 'lost') carvings myself, I think I should stick around for that part of the reveal. (If it helps, to muddy the waters, I could provide my copies of Bob's engravings for review, when that time comes.)
The vials quest perhaps being closest to my heart (vials and leathers being my main claim on the trading floor, I think), I'm definitely in on that. The initial part of the Svarogian deal seems the simplest thing to accomplish, without too much fuss, then the rest of the tangibles dispersed, perhaps a first cautious round of accessorising/equipment upgrading (visits to lockboxes according to need, and don't we have 'expired person' keys to sort out, or am I misremembering?) and we can probably sit down with anybody keen to talk to us about silly pictures at a time of their convenience, up to and maybe even during the work-contribution, as with the Theian reciprocity.
But that's in my head. Realistically, right now, I think at least passing the news that we have vials is enough, via Elena who is the most obvious person to connect those particular dots on the map to convey their avilability. If they want them badly then they could come to us while we're seeing what our other loads might help with, and if not so urgent then we can wander less encumbered, to the workshop we knew (assuming they rebuilt the wall) or wherever else we're told to go.
I'd also like to see the dug-out area that I scared the workers away from, near that workshop. Might even be where we need to go!
