In dark souls 1, New Londo was flooded to maintain the Abyss that was residing within (that Kaathe caused). In Heide's tower of flame, it has also been flooded, but it seems to represent the Anor Londo architecture. What I am getting at is that the Abyss is under Heide's tower of flame (explaining the Old Dragonslayer's manipulation of hexes) and it was purposefully flooded to maintain it.

Now if you go to pull the lever to bring down the drawbridge, look behind you and try to see where you came from. The building in the distance has no connection to the mountains that you came from. From Majula, you can see the buildings in the distance, indicating that on the other side, is Heide's tower of flame, but there is no connection to the rock formation.

So what I beleive is that Heide's tower of flame is the reminants of Anor Londo "if" the chosen undead in the past has left the flame die out, leaving Gwyndolin to almost "refresh" his illusion, and flood the city like New Londo and the way to Heide's tower of flame has crossed between the "fissures of time". I am also saying that what happens in Heide's tower of flame and No man's warf isn't actually "happening", it is Gwyndolin's illusion (but since you are able to retrieve items from the enemies and corpses, it seems that Gwyndolin's illusion is failing gradually).

Now I have no idea what and where the floodgates could be so if you can leave your ideas in the comments that would be great.
