Corrig and Ylon

 Corrig was an Earth-Master and a great harpist.

“He made a harsh, incredulous noise, and saw the harpist finally, beyond the fire, his harp made of strange bones and polished shell, his face lost in shadows. The face seemed to lift a little at Morgon's voice; he caught a flick of fire-scorched gold.”

 “His eyes in the dim light were pale, flecked with gold.”  

“Morgon, still on his knees, watched the figure breaking through the web of shadows, the hair weaving into darkness, the face sparse, shell-colored, the eyes heavy-lidded, blue-green, gleaming with their own light. The body was fluid, blurred, the colors of foam, the colors of the sea; he moved without noise, his strange garments shifting lights the colors of wet seaweed, of set shell.”

During the Earth-Masters’ Civil War, he sided with Eriel and those Earth-Masters seeking to gain more power.  He sired the half Earth-Master Ylon with Oen’s wife as told in the riddle below.

"Oen's land-heir was not his own son, but the son of some strange sea-lord, who came into Oen's bed disguised as the king. Nine months afterward, Oen's wife bore Ylon, with skin like foam and eyes like green seaweed. So Oen in his anger built a tower by the sea for this sea-child, with orders that he should never come out of it.  One night, fifteen years after his birth, Ylon heard a strange harping from the sea, and such was his love of it, and desire to find its source, that he broke the bars on his window with his hands and leaped into the sea and vanished. Ten years later Oen died, and to his other sons' surprise, the land-rule passed to Ylon. Ylon was driven by his own nature back to claim his heritage. He reigned only long enough to marry and beget a son who was as dark and practical as Oen, and then he went back to the tower Oen had built for him and leaped to his death on the rocks below."

Ylon, by his very nature, was driven with longing for power.  Corrig promised to give Ylon this power through his harping.  Ylon followed this call into the sea.  Ten years later One died, and Ylon became the land-ruler of An.  He filled this post only long enough to sire an heir.  Then, realizing that as a land-ruler he would not be able to return to the sea, he commits suicide.  Throughout the six centuries that followed, none possessed the powers of an Earth-Master until Raederle of An.

Corrig, at Herun, played for Morgon the death of Hed while also preventing him from moving.

Withering your voice, as the
roots of your land are withering.
Slow your hearth-blood
slow as the dragging waters,
the rivers of Hed.
Tangling are your thoughts
as the yellow vines are tangling,
drying, snapping underfoot.
Withering the life of you
as the late corn is withering...
Dry, dust dry, the earth
the earth of you, land-ruler
lord of the dying. Parching the fields
of your body, moaning the wind
of your last word
across the waste of them,
the wasteland of Hed.

A struggles ensues between Corrig and Morgon in which Corrig takes various shapes. 

“He held the blade of it, silver-white, half as long as himself; strange whorls of design wound down the blade, delicately etched, snagging the light from the scattered embers. The hilt was of copper and gold. Set in gold, fire sparkling in their cores, were three stars.”

The final form Corrig takes is a Starred Sword.  This shape causes Morgon to loosen his grip.  Morgon flings the sword at Lyra gaining her attention.  She picks it up but drops it when it moves.  Corrig reverts back into his own shape.  She throws a spear missing him but encourages Morgon to grab the spear.  He does and kills Corrig.

“There was a movement in the sea-colored eyes like a distant, faint flick of a smile.”
