Iron Fist of Pelor
I think it's fine to have a ninth-level pixie sorcerer helping the PCs out, actually. There's no problem with an adventure in which the PCs are primarily spectators.
As long as, a third of the way into the adventure, that ninth-level pixie gets killed savagely by the hunter, and the characters find themselves alone in the hostile woods, hunted themselves.
If you do this, give no sign you're going to do it: the pixie sorcerer should be sympathetic, admirable, powerful, like any other NPC ally you'd create. The death should be a terrifying shock.
What if you give the assassin the power of illusion? Perhaps a homebrew spell, a phantasm, that deludes creatures into believing they're fighting something else? The assassin may be weak individually,but might "recruit" the PCs into helping it kill unicorns, by the simple conceit of making the unicorns look like worgs, and making the PCs look like hobgoblins.
