To change the topic slightly, I keep finding myself amazed at the stunning piece of diplomacy the Eonir have crafted despite being isolationists for thousands of years.
When their territories were being encroached by beastmen, goblins and Nordlanders (insert your own "who smells worse" joke here) they mass converted to a neighbouring god in order to build a military alliance with Middenheim and the Cult of Ulric.
When this alliance got entrapped by the Grand Theogonist in imperial politics, threatening the intervention of the Emperor, they roped in both the Colleges of Magic and Karak Eight Peaks by headhunting Mathilde, not for her skill in diplomacy or intrigue, but for her skill in understanding foreign magical perspectives, which has a duel purpose in both being able to develop strategies against the goblins and beastmen but also by tasking her to investigate a lost magical wonder.
Now the political situation is no longer deadlocked; we've got Nordland and the Cult of Sigmar on one side, and Middenheim, the Cult of Ulric, The Colleges of Magic and Karak Eight Peaks on the other. If the Emperor now chooses to become involved, he must side with the Eonir or risk alienating both the Colleges and his dwarven allies, and the Cult of Sigmar can't protest because of their religious commandment to always help dwarves. So essentially it's just Nordland against half the Empire now.
It doesn't matter if Mathilde fails to divine any of the secrets of the waystones. It doesn't matter if she can't create a counter to the lore of the wild. It doesn't matter if the whole thing ends up being a useless boondoggle that drains the coffers of three different nations.
Because the Eonir have already won.
They've enforced their land claims. They've secured military allies. They've built diplomatic links into some of the most powerful institutions in the Empire. They've opened diplomatic channels to Empire and the Karaz Ankor, who now have to treat them as an equal.
And no one can accuse the Eonir of being selfish, manipulative or coercive because their every move has been backed with sincerity. They do believe in Ulric. They do want to restore and use the Waystones. They have stayed within the letter and spirit of the law, and you can't even hold them accountable for the deaths and displacement of ten's of thousands of Nordlanders, because it was really their own fault for being so greedy, and besides, who even cares about some grubby human peasants anyway?
