A part is an understatement. None of this would have been possible without you and yours.
Our success has also served to solidify our understanding of cross-rift travel.
The Ascians rejoined reflections to the Source by instigating elemental imbalances. These imbalances weakened the barrier between realities, causing the aether of a reflection to flood the Source.
But why is it that reflections are predisposed to rejoin the Source? Why have they never merged with one another?

Thou art suggesting there is a unique property inherent to the Source─one responsible for such an outcome?
Y'shtola
I am. 'Tis my conclusion that, as the point of origin for the reflections, the Source has an innate "pull" over them.
Hydaelyn, I believe, sought to suppress that pull, which is why She was created with the power of Light─of stasis.
Meanwhile, the power of Darkness─of activity─reigns in the void. Hydaelyn's influence would naturally be weaker, and this manifested in the form of planar fissures.
