aren't the humans doomed to prolong the age of fire anyway since they can't survive without it? that is what i thought when i made the choice. i don't understand why the primordial serpents would have different motivations though.
the age of dark is also called the "age of man" so no, i don't think that. the gods are the ones who need the age of fire to stay in power. i think the serpents are just opportunists who side with whoever comes out on top. some ppl believe that frampt and kaathe are one and the same btw
that's interesting.
from the wiki about dark ending:
The player's actions have plunged the world even further into chaos, as those who might have saved it are dead, gone, or Hollow. In the end, the player has become the "Dark Lord", ruler of the world, but with the link between the bonfires, the only things holding the world together, fading, there is little left to rule over.
as i see it the choice is between liberating humanity at the cost of the world eventually becoming dark and falling into chaos or sustaining humanity under the ruling of gods.
however this might dispute that:
The Age of Fire, in its final death throes long before the player was even born, recieved its just end with the death of whatever remained of Lord Gwyn. His desperate action of linking the bonfires,which had only succeeded in prolonging the suffering in the world, would lie dead with him. Now, under new leadership, the world can finally move forward into the Age of Darkness and perhaps recover some of what it had lost.
it's really hard to make out if humanity is sustainable during the age of darkness.
i don't have a problem with the ending being as much of a grey zone as it is but what you have to inform your decision is so god damn ambiguous.
