All this talk about forging and preparing alliances kind of triggers my paranoia-gland (yes, it is a gland, not a *snicker* bone. …that’s just basic anatomy, people!).
What kind of evil lurks in the shadows that the Archon might need such an impressive force drafted from wolves, amazons, elves, minor sorcerer-clans, possibly at least one tribe of orcs, various previously unaffiliated myths and cutely-insane demonkitty-commanding sisters?
I can see dear old dad making shady deals with forsaken myths, forgotten gods and extraplanar evils in his megalomaniac attempt to reestablish power and influence over the bloodline. But you don’t exactly need an army to deal with that, do you now? Either the exiled patriarch does a Loki and summons his new masters’ goons in exchange for some mystical McGuffin or at the next possible occasion he, as the currently known threat, will be dealt a swift magically enforced kick to the nuts and some TLS-style diplomatic intrigue.
