It's so terribly popular to hear lectures on the grass not really being greener, etc., but I'm struck by how remarkably untrue that is. Lord knows for all the smell and the noise of this world, I don't care to go home any time soon, either. At least here death approaches the avoidable and it's rare to come across bands of marauding vampires or have a piece of moon lobbed at a city by some bored god or turn a corner and find yourself face-to-face with a scamp or a dremora or a dragon...
Leaving my world has always been a popular pasttime despite it being not technically possible, though.
