You have to scare the robot in the dungeon by going in (find way in in mordreds hideout between hay) and get the owl (merlin) to grab it for you.
You move Merlin to the bomb and click it. It's very simple.
It was sung by Morgan La Fae to her child, Mordred, as she planted the plan of killing King Arthur and taking the throne and ruling under his mother.
It is about mordreds mother Morgan(a) singing her son who she had with her half brother, king Arthur. And it's about how king Arthur is bad and Mordred deserves to be king with his birth-rights
Merlin is in Mordreds secret hideout which is locked by his key and hidden my to stacks of hay. If you get the key form the secret society and go inside, Merlin will be asleep near his nest. You can wake him by jumping near him. He'll fly out. You'll need to release the mouse that you captured form the princess' room. After that, he'll take a liking to you ^.^
