User blog:CNBA3/Fairy Tail Arc Concepts

I believe that in most of the arcs of the manga there is a certain concept that is shown by the plot, characters, style of the story, or just frequently used. What do you think each arcs' concepts are? and what are the reasons for them.

My opinion:

Lullaby: Change

Galuna Island: Rivalry

Phantom: War

Tower of Heaven: Freedom

Fairy Tail Battle Festival: Family

Oracion Seis: Chaos

Edolas: Greed

Tenrou Island: Fear

Grand Magic Games: Rebirth

Rule: Please do not make Nakama jokes!
