They're pretty skilled sorceresses, though; they'd probably be able to work out what happens when they "die" here, and it's certainly something they'd be interested in researching. I tend to think that if the Fetch don't have any reason to believe that death takes them home--and they're definitely not suicidal--then we don't have any reason to believe it either. Although you can if you want, of course. :-)
