…the crack between the worlds was more than a metaphor. It was rather the capacity to change levels of attention. (Ring, 279)

He told you you went through the crack around ten in the morning. So, on that day, ten in the morning became your new time.
My new time for what?
For everything. If you remain a man you will die around that time. If you become a sorcerer you will leave this world around this time. (Ring, 286)
