I still belive that the Dreg Heap and the Ringed City are Lordran and Oolacile, respectively. During the fight with the Demon Princes, you see quite a bit of architecture reminiscent of the original Firelink in Dark Souls 1, the Kiln of the First Flame residing in a giant tree underneath Lordran (if the location is vastly different due to the white staircase beforehand) is also the same tree in the Dreg Heap in the DLC and final area of the main game, and much of the lore behind the Ringed City matches that of Oolacile's, being a kingdom of men and playing a big part in the connections of the Abyss, bringing both the Dragonslayer Armor being corrupted by the Abyss and Darkeater Midir being made the guardian of the City against it. And considering that these 2 places are the only locations in Dark Souls to find Humanity sprites in their physical animate forms instead of simple consumables, it shows a lot of similarities that can't be dismissed as simply reused assets.
I understand.... nothing
