I just hope that everyone voting for the Waystones has by now realised that it will be Mathilde leading a research-project, bringing in experts from several very stubborn factions and trying to get them to work together. And excercise in Diplomacy over learning or martial.
While actual research and possibly even a bit of dungeon-delving for old lore might have a place in the task, it is not the meat of it, so to say. Our further information on the topic was mostly the history of the Eonir and the War of Vengance after all, not a list of practical starts.
It would be sad if anything here wins due to wrong expectations.
Disclaimer: Written to my best understanding of the situation, might be wrong.
Mathilde's learning is going to be useful for establishing bona fides because there's no way a snotty elven archmage will be impressed with an ignoramus (and understanding and collating all the research will be a learning based task).
That said Mathilde will have a lot of diplomatic ground to cover in basically all four leading options. Hopefully this will give an opportunity to level up diplomacy.
