Boney said that in return for RoW and opening the trade route they might be prepared to send Eonir mages to lecture at the Colleges, which is a big deal.
That reminds me that I kinda want to do an action where Mathilde gives a lecture to the Eonir. Probably the Waaagh and Peace one. It's not sharing any new information (the Eonir already have notes from the first lecture), but it's novel enough that I think it would impress the elves. Sarvoi could probably help set us up with an auditorium and an audience.
