Igos du Ikana

Igos du Ikana is the long dead king of Ikana Castle.

To defeat him, you must burn the drapes with the Fire Arrow, letting the light in. Then, you must attack him several times right when he's about to attack you. Watch out for his head that comes off, as there is no known way to counter it. If it gets to you it will latch on to your face, just run away until it comes back to its body. Then when he falls down on the ground, shine the light on him using your Mirror Shield to defeat him. Afterwards, he will teach you the Elegy of Emptiness before disappearing.
