Cause of ascian calamity and rejoining elemental

[Ilenya]

I mean, if it's really important that they cover all the elements and both polarities, then we know what the next will be: Light, again. Because they've yet to succeed in causing a Light Rejoining. They did Darkness twice, it's true - but it failed the first time. Light failed this time (albeit in a significantly less catastrophic manner), so try, try again!

I've been assuming, though I could be wrong, that they only needed eight Calamities. That would push the entirety of the balance tilted towards the source, and the rest may just naturally fall on their own without needing to deal with all the silliness they've had to do for a while. It's a little hard to say, though, because no one's said anything about their plans beyond the Eighth Calamity.
