Duality

Simplest way: use the names of relevant mythological entities as descriptors in your eloquent intonations. Especially Greek and Roman. It's the sort of thing that turns "the edge of otherworldly darkness" into Poe's "the night’s Plutonian shore". The names of the Muses and most of the areas and inhabitants of Hades are required reading in this area.

Also, thesauri that give you words that are known by most readers but exotic to all are extremely useful. On this, you can build an edifice of artifice for reader bliss and avarice. Imbuing your descriptive one-liners with poetic meters also make an incredible difference with regards how hauntingly memorable they'll be (moderately mediocre example: the previous line). Fun writer tips all round. 

I do believe Avarice is the want for specifically power. They do say that Knowledge is Power, but don't think its really something that can be "stolen" from you, per se. Or at least not directly from a book.

"Give unto me all of your precious information, thou magical tome! I shalt absorb these words into my braincase!!"

 There's a bit of a hit & miss with being too flowery of prose! heh! 

Objection! It's the lust for material gains in general, which quality flowery prose can definitely provide to you. In business they call them buzzwords, and collectively they form the mysterious and ancient Language of the CEOs.
