The falcon of the sun is a song about a falcon that claimed it was born from the sun.
The intro start with a falcon arriving in a forest, and observing the inhabitants.
The first verse is about the falcon deciding it wants to be a lord of the forest like the wolves and owls are and how to accomplish that.
The chorus is the falcon claiming it's born from the sun and since that's where all life comes from,
that it should be in charge.
The second verse is about the falcon tricking the inhabitants of the forest to believe its claim.
The third verse is about the changes the falcon makes.
(chorus again)
The fourth verse is about everything that goes wrong in the forest due to the falcon's changes.
The bridge is about the forest burning down and how the falcon dies in flames.
The outro is like the chorus, but with the twist that the falcon is doomed to fail instead of being in charge.
Goose's parents are fond of the song and know it to be a more recent adaption of a story about the Shepherds, but they do not know the origins, significance, or symbolism.
