People obviously have no idea how to pronounce the word "pyre". Listen how to pronounce it here and add the Em to it. And while we're at it, the word Demesne is french and sounds like Da Main or Da Mean
I've come to the belief that some zones just don't need to be pronounced. Qeynos, Txevu, Yxtta, Vxed, Qinimi (lots of GoD zones), Lxanvom, probably a couple more that I missed. But, I did actually look up the pronunciation of Empyr and all of the ways listed in this thread are correct depending on the location.
