A native North American nation would be nice; although I have to confess I'm not too keen on nations with flimsy infantry.

The suggestion/quibbles:

A level 4 priest is quite unnecessary with such a diverse selection of sacred mages on offer. Doesn't fit the theme particularly well, either, IMO. If it did, it would have a cooler name than 'high priest'.

There's probably a few too many low-level mages; I'd give the witchdoctor the boot. The name is already taken by Machaka, for starters. The random socery pick doesn't fit the theme very well either, IMO. Astral and nature they already have in abundance, and death and blood aren't really very thematic for what seems like a good and noble nation (you say it yourself: this will not be a blood nation). Additionally, the nation is already swimming in randoms, is another really necessary? And finally, the witchdoctor seems awfully like the Jotun Vaetti Hag.

The only elemental magic I would consider for this nation would be air; seems thematically correct, given their stealth, illusion and archery. Giving them access to all elemental paths is way too much , especially when they've got so many random picks already. I'd avoid giving them a reliable source of Earth magic, in particular; it's one of the most powerful magic types, IMO, and not to be given lightly.

Having them as an nature/astral/air nation with a solid dosage of randoms is plenty.

I agree that they don't need an assassin.

I'd broaden the 'ancestral herd' spell to include other spirit animals as well; wolves, hawks, bears, lions, etc. Keeps in VERY well with the theme.

Have you considered making their ethereal units mistformed instead (if it's even possible)? Would add a bit of distinctiveness to the theme, versus Vanheim's glamour and Soul Gate's ethereal. Could be awfully powerful, I have to admit.

I think you should try and achieve more of a balance with regards to resource cost. It's not much fun to have to go 'either-or' with nations that have a mix of ultra-resource-cheap and ultra-resource-expensive units. Vanheim I think has a good balance here, yet still has plenty of diversity.
