Dragonsong suggests Shiva (the historical one, not the Primal summoned in her supposed likeness) was the original ruler of Ishgard and was on friendly terms with the dragons until something created a rift between them. She then sacrificed herself in some manner to prevent the Dragonsong War, but it was for naught because of some manner of treachery.
So... no, I don't think the real Shiva wanted any of this.
