I've seen conflicting information about who can ride which Ethereal Mounts. Most information I find online says that many of the vet rewards ethereal mounts you have to be old enough to claim it in order to ride it. I have however, seen references from players which suggest that restriction was removed from all Ethereal mounts. So, before I purchase something I can't use are there any restrictions on ethereal mounts? I'm especially interested in the Cu Sidhe. Thanks!
