Nightfall
Sage of the Scarred Lands
First off, NP Psion/Alan. I'm glad I could TRY to help.
If you REALLY want evil outsiders, then I'd suggest using a few blade demons, followed up with Leonine demons as shock troops/front liners. Course since you SAID devils, Legions automatically comes off the top of my head, so probably instead what you SHOULD try is that the Witch of the Damned (the one with the big cabal of witches) is helping out, by having a couple of her high preistesses summoning and calling devils of all stripes. Iron Devils would definately work to your avantage. Still might be something to add. Demons I can do.
My idea, there's a HUGE chuck of ice and snow where locust demons breed, since they don't care for WHERE they hail. They are looking for a way to send their spawn forth and despoil and ravage as much verdant wildlife as they can find. Plus they have some help from a colony of Milicend(sp) (Fungi people), that are looking for better place to settle. Also, the attention Drakar is getting from Hell, also draws the ire of one of the Demon Prince's underlings, Graz'zt shamaness Night Hag who wants to prove her worth to him. So she's been keep taps on the Blood War and of course many different primes. So now she's involved, via some low level operatives, in subverting much of the arcane power of Drakar as possible. That help any?
As for the Animator/Unfailing, yes they are prestige classes from Hollowfaust. (I know I'm pushing this hard my friend but I cannot say ENOUGH good things about Hollowfaust.) But no they aren't.
I just created them on the fly, BUT they came into my head rather quickly, so they have life to them, as I picture Rickon as kind matured vetern spellcaster with the qualities of a Julius Caesar and Mark Anthony mixed with a touch of enlightened despotism added in.
I don't get Dungeon, so no I didn't know that. But since you already mentioned that, perhaps the Kobold cannot sustain the rescepticle any more. Thus you might have a wild uncontrolled shield guardian to content with along with uncontrolled automani too.
Anyway, I hope SOME of my ideas take root for you. Good luck tomorrow.
