There were a few grammatical errors in the text you provided. Here is the revised version:
There was a greater influence of Norse mythology on America than Kyrie wanted to admit. From the Lindwyrm to himself with the power of Skoll, Yggdrasil, Hel, and Valkyries… America has become the playground of those pagan gods.
If there was a time to know why, it was now. "I never inquired about it, but I guess Loki made something here to wrong Odin; this is why the All-Father is so pissy about this place and wants it destroyed by yesterday." The dragon snickered, judging Kyrie as a fool.
It was laughing over the fact that the city would be destroyed anyway because of the Asgardians and they just gave him a shining new lair for it to enjoy. Kyrie smiled; he already had everything the dragon could give him. Now it was time to end that creature.
