Just to clear things up, do the lost have to hide what they are? In some bits it implies the lost are actively hunted but in others it implies the lost can be more or less accepted, but still suffer stigma.
So, can a character openly be a lost? I assume so as if they were hunted/killed on sight it wouldn't be a stigman, it'd be a secret they'd have to keep, not a stigma.
