Whilst our world is called Hydaelyn it is separate from the mothercrystal herself of the same name. Hydaelyn the mothercrystal exists in the aetherial realm and all aether in the world of Hydaelyn comes from her and returns to her via the lifestream.

Hydaelyn is both the world and the creator, though they are actually separate entities sharing the same name.

I wouldn't think we created them via some summoning equivalent though. Ramuh's suggestion, when paired with Lahabrea's (potentially false) explanations, would mean that Hydaelyn created the mortal races and broke the balance in doing so. That may not be the case, and even if it were we have no idea what that actually means for the wider scope of the story. If Hydaelyn did indeed break the balance as Lahabrea suggests then I would assume she had a reason for doing so as she has put her own existence in danger as a result.
