" The sword was called Kaledvoulc'h, which means hard lightning, though Igraine prefers to call it Excaliber, and I shall call it so as well because Arthur never cared what name his longsword carried. Nor, did he care about his childhood, for certainly I never heard him speak of it. I once questioned him about his early days and he would not answer. “What is the egg to the eagle?” he asked me, then said that he had been born, he had lived, and he had become a soldier, and that was all I needed to know. "

― Bernard Cornwell , The Winter King (The Warlord Chronicles, #1)
