Yes, even though Fedora 20 will mount neither volume, Ubuntu 14.04 will mount the /dev/MORE_VG/MORE_LV partition.

That means the header was at least partially overwritten.
Can you post or send me a hex-dump of the first 1024 bytes
of this device and the other one?
Command to do so is, e.g.
head -c 1024 /dev/FINALFRONTIER_VG/HOME_LV | hd
This will not compromise your security.
Yes. Something seems to be running amok.

Another queston: After Fedora 20 told you both were not
valid LUKS devices, could you still open the one in Ubuntu
that you could open before?
