That part about the gate is a bit ambiguous.

At one point in time it was said that the dragons decided to come to the future because the magic power in the past was low. If that was the case where did they get the power needed was using the eclipse in the first place.

I believe that it either need power to collect power only if celestial magic/ wizards weren't around but that is just my belief.
