Storm-Threnodies can be acquired if you have the profession of Trickster. I get one every week :)

Night-Whispers can apparently be acquired from digging at the Shrine of the Deep Blue Heaven. One of the possible treasures is 2 night whispers. It may take a lot of digging, but it can be done earlier in the game than the other options I looked up, and it doesn't require a "rare success".

Seeing as how no-one has added beyond this, I'm guessing they are hard to find. If YOU do it, tell us what's next?
