About the 1st World, i don't know if you have realized but up to when the Sun God appear
the whole initial portion is connected.. The people who succumbed to their Greed or Desires are the same
people who enslaved themself from touching the Forbidden Sun, they are not random Slaves..
The typical word for Slaves is '' Dorei '' 奴隷 , where here Oda made a word that do not exist in the
Japanese language to my knowledge, which is '' Reijin '' 隷人.. It of course translate to Slaves or Slave
People..
On the 3rd World, it states at the end that the '' Sun returns '' or the '' Sun will return '' whatever translation
doesn't matter, it's a prophecy it hasn't happened yet.. It doesn't mean that they will rediscover the real
Mother Flame of ancient void century technology, well it could too.. But the true meaning is that the '' Sun ''
will return to its '' Original State '' pre 1st World if you will..
And, the '' Sun'' returning is intimately tied to the previous line, Guiding the '' World '' to its end.. For the
Sun to return the World as its known has to end in some way shape or form..
