So regardless of wheter I end up voting yes or no, here's my opinion on the various options:
[ ] [SCOPE] Laurelorn (0)
While this seems like the least fraught option politically, I actually see this as a snub towards Marrisith and the Council of Tor Lithanel. We don't have the right to give Tindomiel exclusive construction rights in a realm that we have no authority over.
[ ] [SCOPE] Northern Provinces (+1)
This seems already like a better option than the one above and it comes with a +1. On the other hand it includes Nordland, which will be a tougher nut to crack diplomatically than probably most other Provinces. So if we take this option there's not much difference than taking the one right below, which both gives an additional +1 and allows us to potentially negotiate just with the Emperor for permission instead of negotiating with a bunch of ECs separately.
[ ] [SCOPE] The Empire (+2)
I think this one is my favorite for now, for the reasons mentioned above.
@Boney The second and third SCOPE options don't mention Laurelorn and Laurelorn isn't technically part of the Empire (or the northern Provinces), especially according to Laurelorn law. Does that mean that if we take these options we can still claim that Laurelorn itself is not covered by the deal and thus not alienate any potential rivals of Tindomiel as much, due to not having usurped the authority of the Council and Queen?
[ ] [SCOPE] Empire, Bretonnia, and Kislev (+3)
Mathilde has no standing to decide this for foreign nations. If they happen to not like Hekarti I do not want to tell them to go suck it.
[ ] [SCOPE] The Old World (+4)
See above, except even more so and with Dwarves included. Just no.
[ ] [REP] Head (-3)
I don't like how into Hekarti he is. I definitely don't want someone who is likely to included a backdoor for her without our knowledge.
[ ] [REP] Enchanter (-2)
We don't know what Lord Hatalath's speciality is, so this might be worth it.
[ ] [REP] Magical Theorist (-2)
I'm a sucker for theory and Tindomiel might have some juicy bits we won't get from any other current participants.
[ ] [REP] Priest (-1)
Isthien's negotiation priorities have turned me off from involving Hekarti's religious side too much.
[ ] [REP] Heir (-1)
This could be anything. He could be useless and/or tightly controlled by his Head of House, or he could be flexible, radical and underestimated by his own people due to a massive Elven youth bias. If we end up with just +1 favor then this is who I would go for over the priest/ess.
[ ] [FORM] Shrines (+1)
I don't like it much, but metaphysicall speaking I don't expect it to make too much of a difference when it comes to directly channeling magic energy to Hekarti. If we need the +1 I'm tentatively okay with it, angry mobs notwithstanding.
[ ] [FORM] Dedication (0)
I'm worried about the metaphysical implications of this. Angry mobs should be less of a problem though.
[ ] [FORM] Discreet (-1)
I might vote for this out of pure curiosity of finding out who the Empire's god(dess) of magic turns out to be. Getting them worshipped as such in the Colleges might be of tangible value.
[ ] [FORM] Secular (-2)
The fact that they would still take this deal makes me more worried than not. My read is that they could still to some extend get what they want out of this, which I am sure would be more than just prestige and political clout. Given that we can only take this option if we choose a -1 representative and allow them three large nations worth of territory it might mean that a sufficient mass of Tindomiel Waystones still get a decent amount of power flowing to Hekarti even without any tangible dedication outside of whatever opaque "programming" they have in mind.
