I have a proposal. Right now, we have a finished design, and several theoretical ones, but we don't exactly know much about how we can or should use them. Therefore, I think for next turn it would be a good idea to:
1) Use Laurelorn as our testing site. It's a mostly controlled environment, where we already have a base of operations, close to the Archmages and High Mages we need (as well as everyone else we want to bring to Tor Lithanel), and to the first production line (handled by House Tindomiel, as per our agreement). We can see what's the best way to set them up, how well our river/leyline transmission works in practice, what are the production speed and the logistical problems, where are the bottlenecks, how easier to make does the storage get, and whether there's any unexpected problems. I'd have preferred to start fixing the most problematic places already, but we really should look into them first, which brings me to the next point.
2) Take a look at the places we need to cover. Most of the Old World will presumably be similar to Laurelorn, but the highest priority locations (Kislev, Mordheim, Sylvania, Forest of Shadows, Middle Mountains) very much aren't. We need to know how bad it is (or more accurately, what flavor of 'really bad' each place is), what do we need, and how we should adapt our Waystones to deal with them. In particular, I'm thinking of a Kislev-Mordheim-Sylvania roadtrip, with Zlata and Niedzwenka for the first, and the rest of the gang (Egrimm/Cadaeth/Sarvoi/Aksel/Tochter) for the other two.
3) The following turn, we'll have a far better idea of what to do: what new design(s) do we need, where can we just start putting our current model of Waystones, where and how to set up new production lines, etc. We can thus finally get started with mass production, make a schedule for the Project's next steps, and leave for the Elfcation at the end of the turn.
