I'm going to repeat my suggestion that we enchant the Thurible before we bookmine because I think it'll be really useful to have. We don't know what's underneath the ruins, and being able to flood the tunnels with undead repellent will be really important. Yes, it'll cost 5 CF to hire an enchanter, but people were already talking about spending CF on a Celestial to divine the site—although personally I'd rather use the Gambler—and we generate a lot of CF anyway. We could even donate it to the colleges after we're done with it for more CF.
We could even do the windherding action in the same turn, I guess. Get them both out of the way before Eike turns up, then do the scribe+Great Deed combo, and then speak to Vlag.
Anyway, my idea for next turn would something like:
Plan: waystones and windherding
2-3 waystone actions
1 Eonir diplo action (explore the city, assist a person or house, give a lecture etc)
Windherd
Bookmine w/gambler
Apprentice teaching lessons
