Calamities explained

[SKgaming]

Ok thanks for this.

But what elemental unbalance would have occurred in the first if the Warriors of Light had indeed killed Cylva (The Shadowkeeper)? Would it have been a Shadow Calamity on the source then?

Is it that the timeline where the black plague was unleashed on the Source the result of Cylva actually dying? and the current timeline is one where she lived, hence avoiding the calamity from occurring on the source?

Sorry I still find this all very confusing.
