You were forced alongside 49 other people to participate in ‘The Long Walk’ And one of the members of A.H.E.S (I think that’s the right name) explains the rules

A.H.E.S Member 1: The rules are simple: from this point on. You move or you die. Stopping for too long will alert the Watchers (code name for member) Stay on the marked paths and collect what you can. Only one of you will reach the end. Good luck.

There was a Brief silence until it started. And now you needed to walk OR DIE.
