Gal can summon rain with his singing, but the lord prohibits him from praying for rain because he only wants to monopolize the water source.
He sang against the rules and finally summoned the long-lost rainstorm.
The rain is carrying shadows that do not belong to this world, hovering under the rain clouds.
The shadows devour the lord's guards, but the lord falsely accuses Garr of attracting the demon.
The imprisoned Garr discovered that the lord had been feeding these alien creatures on the despair of the villagers.
Ella, the deaf-mute sister, is the only one who can see the shadow's true form.
When the lord tried to sacrifice Ella for power, Garr sang a forbidden song in the rainstorm.
The fortress collapsed in the flood, and the shadows hovering in the sky screamed.
Rain is no longer salvation, but a channel for the arrival of alien creatures.
Gal held Ella's hand, and his singing became the last protection amidst the flames and floods.
