Before meeting the stranger in "The Great Builder," the Aesir lived in a state of complacency and arrogance. They believed that they were the most powerful beings in the universe and that nothing could challenge their authority. They were content to live in their grand halls and enjoy the fruits of their labor without any thought for the future.
However, when the stranger arrived, everything changed. He challenged the Aesir to build a wall around Asgard that would be strong enough to keep out the giants. The Aesir were initially dismissive of the stranger's request, but they soon realized that he was not to be trifled with. They agreed to his terms and set about building the wall.
As they worked, the Aesir began to realize that they were not as invincible as they had thought. They struggled to complete the wall, and they were forced to rely on the stranger's help to finish it. This experience humbled them and made them realize that they were not infallible.
After completing the wall, the Aesir were forever changed. They no longer took their power for granted, and they began to think more about the future. They realized that they needed to be prepared for any challenge that might come their way, and they began to work harder to ensure that they were ready for anything.
In conclusion, meeting the stranger in "The Great Builder" had a profound impact on the Aesir. It humbled them and made them realize that they were not invincible. They began to think more about the future and to work harder to ensure that they were prepared for any challenge that might come their way.
