it is unprecedented for two of the Five Clans to intermarry, and hence certain parties might be inclined to contemplate what the combination of… bloodlines… might result in. This being a purely academic question."
"Are the Nara in possession of a Bloodline Limit?" Kei asked with a frown. "One has never been mentioned when discussing the Ino-Shika-Chō, and I was under the assumption that all your abilities were simply secret techniques."
"Oh, dear," Shikamaru said, setting aside his remaining hot chocolate. Kei accepted his proposal of mutual disarmament, tipping the coals back where they belonged.
"You left the Mori as a genin, yes?"
"It hardly bears repeating."
"Then, how much do you know about the origins and purpose of the Mori Clan?" Shikamaru asked, simultaneously beckoning her indoors.
A bizarre question. Shikamaru must surely have learned this much information about his fiancée's clan during the Chūnin Exam.
Kei closed her eyes and began to recite by rote. "The Mori Clan was established by the man we know as Mori, one of the greatest warriors to fight by the Sage's side during mankind's earliest days. During the great battle with the last primordial monsters of this world, he sacrificed himself to protect the Sage from a lethal wound. Though the Sage sought to resurrect him, part of Mori's mind had already crossed to the Deva Path to receive its just reward. When Mori returned, the Sage wept, for the man who had saved his life was like unto a puppet, lacking all free will."
As she spoke, she could hear what sounded suspiciously like Shikamaru closing all the doors and windows to the room, which was not at all alarming.
"Unable to offer Mori the gratitude he deserved, the Sage instead commanded him to found his own clan. Then, when children were born to Mori and his ordinary wife, it was found that each one, though a great hero in his own right, shared a portion of their father's curse. Without the power to grant true free will, the Sage instead bestowed his own transcendental wisdom upon them, that instead of being guided by their flawed humanity, they be ever guided by the truth.
"Ever since, the Sage's gift has been known as the Frozen Skein, for it is a vessel for bottomless depths of truth— but as the truth never changes, so those who embrace it can never change."
"Elegant," Shikamaru conceded. "We have one of those as well. Anything else?"
"More of the same with more names and additional flourish, I believe," Kei said. "And theoretical debates over the origins of the name, which I never cared to acknowledge the existence of."
"So…" Shikamaru said slowly, "nothing about the Five rings any bells?"
"Not beyond the obvious. Five Elemental Nations, five Villages, five Kage."
Shikamaru looked away from her for a moment.
"Please find a comfortable seat, beloved wife, while I call for more Shiori-brand tea. I have a feeling that we'll be staying up for a while."
