Yeah, the indies have to go

Iirc, they say that if you're not taking a province a turn, something's going wrong... though, of course, that's for strength 5 indie stuff. Not quite as easy with strength 9 ones. Anyway, that province north of that eastern castle is definitely a prime target. Always wanna' have the provinces surrounding castles in your possession, especially for high resource nations. Same for that province below the r'lyeh one to the west, if it connects with the castle right near it. Above and beyond that, more land, more land, more land. As one critter put it, more provinces = more castles = more mages. The answer to "How many mages should I have?" is always "More."
Those frost fathers can be kinda' nice, by the way. Fairly cheap (more due to upkeep than recruitment cost) and they can spew numbness and quickness around, which I think you've got access to. They're also water searchers via Apsu, if you can spare the gems for it. If you do go for construction 8, you can also make 'em 3w on the cheap, which opens up a bit more to 'em. Nice lil'guys, and sacred to boot, so you can really spew them out. Start recruitin' and keep recruitin', would be my advice. Send packs of them around with your armies, especially ones that are going outside your dominion. Shame you didn't find them earlier, though. They're also alright for banishment spam.
Enchantresses are all kinds of sexy, but not sacred. Upkeep, bleh. Still... is nice find. I find 'em fairly often when I'm doing 75 magic site maps, and it's almost always a nice thing to have.
Beyond further conquest, I'unno. Getting some decent summoned thugs/SCs out would probably be a major combat multiplier and give you a better chance to use that awesome forging shtick ulm has.
High Turmoil + High Luck means you rarely need to worry about money, but it also means when bad events hit(which is rare) they hit HARD. I tend to use that myself.
I go straight order3/luck3 in my standard comp-fight builds (read: Crap imprisoned pretender,
ridiculous scales.). Turmoil/luck gets you a lot more events, but order/luck gets you the
best events. You still get more than normal, too~ Luck is the second sexiest scale to me, right after growth.
