SO I remember seeing something in the gwbw steam forums saying that if Burden gets shocked back to Legin when he’s eaten by the space portal thing, he’s technically aging seven years every time and eventually that will catch up to him. The idea that he might just be “waking up in his younger body” with the built up memories from the last round(s) would fix that, except we know that his previous lives have had some physical impact on the world as seen by the journal, which someone ELSE had.
