Simply speaking the Arc names are entered into the 'FANDOM' based on the major event, faction or person upon which the story progression takes place.

Example: If Alexander III of Macedon created his empire within a short period of time it will be named - 'Alexander the Great Arc'

I hope my 'Answer' was benificial to you.

Thank You
