Prologue: The Road Yet Paved

When Sam & Dean's mother decides to take a trip with Jack & Claire joining her to Red Grave City to visit her twin sister. She didn't expect to find ruins of a partially burned & decaying mansion or a gravestone containing her sister's name. Mary also didn't expect her sons to show up, teaming up with the cousins they never properly met to hunt down demons from Mary & Eva's past.
