I assumed Moonrise Tower was older than that, and the tower and had been there a long time already, but regardless, the timeline doesn't really make sense.

Something that really gets me about Daisy as well is that in a better game, Daisy could have been utilised as a great way for the player to flesh out their character. It could have been a way for Tavs to express what they want, who they were and what their goals are. Instead if we use the tadpoles the game assumes we're evil and want to conquer and destroy, which isn't even going to be true for all evil characters. At least the guardian frames it around giving us power to solve the immediate problem in front of us. That's part of the problem with Daisy, if you used the tadpoles then you're just going to have to make peace with the game deciding you have a particular set of motives and imposing a particular type of relationship between you and Daisy.
