Has anyone ever soloed the entirety of w101?

More in as, has anyone ever soloed every world end dungeon in the game? Maybe excluding catacombs. Is that even possible? I can totally see arc 1 being soloed. I practically did it myself on death. But arc 2 when you hit Azteca and Khrysalis. Those dungeons can be pretty tough if I remeber correctly and so are the rest of the arcs after that.
