Where did the dark crystal go?

I thought it might have held all the souls that were sacrificed to summon Zodiark in the first place. And since we defeated Zodiark, we freed all those souls, so the crystal is gone now.

That or it's simply crystallized aether like Hydaelyn's crystal was said to be. Zenos went in that pit so he may have ate some of it (he loves eating these crystals, apparently xD)
