"Why do we grow more scared as we get older?"
Hundreds of seasons ago, a wizard's war scarred the earth, leaving a malevolent fog blanketing the land, and carrying the settlements within it like ships adrift at sea. The phantoms the fog creates are deadly to adults, so children must guard the walls now, and care for each other.
Ogma watches the fog from the walls of her windmill town. What felt like a game as a child becomes more of a creeping dread with each season she gets older.
"Because we know better."
Ogma's town is attacked—alien caravanners who roam the fog in inhuman forms have come to kidnap the children, and Ogma is lost in the fog. She must find hope, find courage in herself, and find her friends.
