During another visit to Jotunheim, Thor and Loki met Skrymir, an especially large giant. He was so big that when they wandered into one of his gloves, they thought they were in a mansion and slept in one of the fingers. In the morning they found Skrymir sleeping, and Thor tried to crush the giant's head with Mjollnir. Skrymir simply brushed away the blow as though it were no more than a falling leaf.

I was wondering if they had planned Skyrim to include giants from the very outset, as perhaps the focus instead of dragons. Or is this just a co-incidence? Any thoughts?
