Most of the stuff you are discussing is ambiguous because of a bad English script.

Your Blessing of Light isn't gone forever, it's just sealed.
You're being tested to see if you "qualify" for a better power than BoL that Midgardsormr could give.
The Ascian showing up to wreck your day is not something Midgardsormr planned or intended. However your response to his arrival was part of the test.
There's something very wrong with Ishgard, a cutscene in a previous patch should have clued you in on that.
The dragons getting mad and wanting to raze Ishgard to the ground is a response to something being really wrong with Ishgard.
