The only people that Ielitha Dema intentionally takes the souls of are the people that she's exacting vengeance on for somebody elses' behalf. Otherwise, it's entirely an accidental property of Aedora that people end up there, usually still alive (although they might be transformed into Shades when they eventually die, I'm not sure).

However, I do imagine that some of her more dangerous artifacts could let Aedora bleed through into Anadara, and would subsequently pull everything effected with it back into the realm proper when the effect ended. Not the worst fate, but certainly not one most people would desire.
