So, to poke the ball a little bit, here's a topic for discussion:
How do the various types of Evil outsiders interact with each other and other outsiders and why? I'm talking about groups, not individuals. For instance, we seem to have have come to the conclusion that Night Hags treat most hordlings like people treat wild animals - they would shoo a wild dog away from their garden but can get in trouble if they get surrounded by a pack of wolves in the woods. Do the hags know some secret, as per their forte, that might give them the upper hand over the stronger or more numerous hordlings in such circumstances? The hags act as merchants to both sides of the Blood War, but how do they deal with the equally opportunistic Yugoloths, particularly since they have such drastic uses for larvae. How do hags act around Gehreleths, Slaadi, Modron, Rilmani, Celestials? How about hordlings in the same circumstances?
Anyway.... share your ideas and discuss.
Yay, for ball poker Iavas.
It is interesting question since each hag is in heart individualistic and they work in wery small groups. I mean we all know basic relatons of mayor planar races but relatons of "minor" planar races like hags we know practicly nothing (exept from acts of individuals from various adventures).
Well I think that hags are on lower planes treated with mix of fear and respect, after all they are keepers of many secrets (and knowledge is power), also their magic is different and it bsecrets are unknown to rest of muliverse so no hag will have same tricks in their sleves.
How hags deal with races of lower planes, well I think the each hag is smart enough not to mess with mayor races with their plans, plots and experiments, they can mess with them on individual level but not on racial one. I think their relatonship is strictly of buisnes nature at arms lenght: the hags are best provider of goods (larve) and that suits the fiends just fine as long they dont get involved in their schems.
Also it is ironic that eweryone goes to hag for the advice sooner or later, so I guess that hags are treated as sort of asset that can be exploited (but with caution), so there is posibility that the hags are viewed by fiends as "mostly harmles", useful but unimportant in grand scheme of things, cute old grannies that tend their horsies and steal bad dreams. And that is the exactly kind of public image average hag would want.
Then again there is alvays misterious partnership betwen Vaporighu (PSMC Apendix 2)and hags: Vaporighu can summon hags to its aid but it use that ability not often since it must repay hag in some way. Limits of that kind of relationship not even fiends want to test to extrems, after all even greater fiends fear Vaporighu.
Als here is another idea for another service night hag could provide for Baatezu side of blood war: theycould provide, rise and breed and train nightmires for narzugon cavaliers.
