That's a...strange topic. I've read much mythologies about fate and selfsame lots of philosophical concepts about fate and its constructs. I still struggle to find my belief: Do we live in an indeterminate universe? Is everything we do sealed? 
Is it sealed for a good reason?

Again, I still feel like that this might just be another mortal 'arbitrary designated line which tries to describe something out of thin air' kind of phenomena. It's like Wolfdragons describing colors to a Mountain Dragon. Very fickle in the end.
