I imagine the spinemeld titles are a shout-out to the first edition monk level titles like “grand master of flowers” and “master of the north wind”.

Speaking of incarnum, how about all the feats where the authors ran the thesaurus program on “blue”?

Also, every prestige class with the word “master” in it could actually benefit from a thesaurus. Or a different concept. If everyone is a master then no one is, ok?
