Don't know about that, it's too much of a made-up name I think. What does causerie have to do with peaks, in a strict toponomic sense? How did the town got such a name?
And if people "get it", it might be a bit of a give away you don't want.
"Parnassides Peaks" is more like a mystery.
Or "Bragi Hall"
to name some...
Or add a bit of culture from where you've got your inspiration, as in Irish, Italian, Russian, German, Dutch, etc. You might also have a toponym that's named after a famous place from traditional horrorstories.
