Aerospace Center Warehouse Access Terminal Puzzle

[Ralk]

Ive been trying this puzzle for a while now but cant seem to figure it out. Does anyone know the answer to this?

“In the lap of the mountains, the song of a thousand rustlings is crossed by ashen rays.

The wind is calm: the hot rocks hit by an impetuous force.

This is the home of a thousand lives, but only the most fragile and unaware will be interrupted by an insatiable hunger “

Options:
Sun
Moon
Wave
Tree
Fish
Bear

Any help is appreciated

[Edvard Grieg]

The answer is: Tree-moon-sun-wave-fish-bear
