Well, we are off to a good start.
Unsurprinsingly, it's the MoI on one side, literally everyone else on the other. (Granted, it's also because the WP are absent, but still).
In any case, the middle ground seems like the way to go. The first option runs directly counter to both Ling Qi's and the Summit's objective of making the ES-WS something more than friendly-ish strangers/neighbours. So that one is out.
Furthermore, a single MoI favor isn't worth losing all the others, even if MoI favor is really valuable.
Eh. This one is a bit more complicated, but not really that unmanageable. In terms of pure Favorability count, the first or second choices seem like our best options. For long-term purposes, the third sounds like the best - but it sounds like it's going to be too much MoI loss to be safe. Ultimately, we have plenty of ES and WS favor to soak, one way or another.
Option Three is the best idea in the long run, but we're not looking for 'The Long Run' yet, we're looking to set precedent, and Option Two gets us what we need to minimize harm until it becomes more acceptable to properly sort this thing out.
Option 3 would be a lot more immediately necessary if we had chosen the Shared Bases on the previous vote.
With a lot more shared spaces, and with all the travelers going through, it would be paramount to establish the proper rites for hearth-tending, guest-right, road tending and so on.
But since we chose the Alternating Bases, it would be best to keep a coherent line of progress here.
Starting with a small council that can discuss and experiment with inter-border rituals on the Embassy, and expand those further down the line once they had built some turst.
