You were on Dragon's Edge, taking care of Garffilljorg with Heather. Garff kept on crying, then Heather started singing a lullaby to him to calm him down.

[humming]

lullaby: “The sky is dark, and the hills are white, As the Storm King speeds from the north tonight, And this is the song The Storm King sings, As over the world his cloak he flings. Sleep, sleep, little one, sleep He rustles his wings and gruffly sings, Sleep, little one, sleep.”

Garff is now sleeping after that.
