Ser Ilyn bowed before the king and queen, reached back over his shoulder, and drew forth six feet of ornate silver bright with runes. He knelt to offer the huge blade to Joffrey, hilt first; points of red fire winked from ruby eyes on the pommel, a chunk of dragonglass carved in the shape of a grinning skull.
Sansa stirred in her seat. “What sword is that?”
Tyrion’s eyes still stung from the wine. He blinked and looked again. Ser Ilyn’s greatsword was as long and wide as Ice, but it was too silvery-bright; Valyrian steel had a darkness to it, a smokiness in its soul. Sansa clutched his arm. “What has Ser Ilyn done with my father’s sword?”
I should have sent Ice back to Robb Stark, Tyrion thought. He glanced at his father, but Lord Tywin was watching the king.
Does this paragraph from A Storm of Swords confirm that Tywin Lannister reforged Ice into the two Valyrian steel swords meant for Joffrey and Jaime?
"Ned Stark's steel"
when speaking of Oathkeeper. (the whole phrase is spoilerific though). You should be careful asking questions while reading, it is very easy to have plot secrets revealed. – TLP May 1 '13 at 12:22
