Just how responsible for the Flood of Light was Hydaelyn?

[MikkoAkure]

I didn’t think it worked for anyone and no one was the cause except for the warriors of light. Since the balance was tipped so far towards the light and the ascians were defeated, the flood happened (as far as we’re aware, pending news from future Eden quests). The reason for the whole expansion is that the ascians figured out how to make a positive out of a negative.

A completely flooded world of light doesn’t work for the ascians, but a living world with extra aether does somehow.

Edit: Got ninja'd by Cilia who had a better answer than me.
