There really needs to be a guide entitled, "Pimp your Wayfinder."
I love the Vanities, and wish that they had created more!
As an aside, thanks for making me research this a bit more.
I just realized that my GM Baby Bubbles the Hellknight needs to switch to Dark Archive since she has never been played. I've been worrying all this time about how to qualify for the Hell Knight Prestige Class, and now I see that there is a vanity that would let me just join the Hell Knights anyway for Dark Archive folks.
This way I can devote my resources to being an awesome shaman who happens to be a Hellknight instead of wasting a whole bunch of feats to join a prestige class of which the only thing I want is the title.
Hmm
