Ghost Traveler Tales

Ghost Traveler Tales is about an unknown and unnamed traveler, who through no fault of their own is left behind in some form to aid and assist loved ones whom they left behind or loved ones yet to come; in any way possible. All of us go through troubling times and in our despair cry out for aid from someone to guide and help us through what we perceive as desperate.
This story is one of such adventure and a bond like no other. Is the Ghost Traveler real or imagined? Is it a ghost, guardian angel, spirit, figment of imagination, God speaking or just our inner brain, which generally goes untapped? I report, you decide.
