Thanks for the reply.

Those who have done endured strange events sometimes have a “mark of Cain” that leads others to stay at a distance from them and leave them alone

Could you please elaborate on this part? The “mark of Cain” has always seemed like pure fiction to me. I do not understand what it is supposed to refer to, if anything.
