[Additional Notes]
The seal master doesn't have many stories told about her, indeed, little is known about her, except that she is often associated with explosions. While efforts have been made to pin down her identity, the truth is that the only concrete proof to her existence is the remnants of a handwritten sealing textbook, the oldest such discovered, with the Nara mark on the cover. People even doubt her gender, and claim her femininity is only because of a mix-up with Nara Earth, and that he was the third member of the Sannin, the toad-sage, who was an acclaimed writer in those times, although the name and even the subject of his books has been lost to time.
The only tale told about her is about the insult of her brother and the revenge of the Nara. This, as it happens, is the only common thread unanimously agreed upon. The details of her brother, whether he was older or younger, innocent or deserving of the insult, the details of the insult, and the type of revenge all vary, though most people agree that explosions were somehow involved. Some report injury dealt to the boy rather than insult, but the effect is the same. These stories have long served as the classic set-up for any aspiring novelist to test their imagination, until there is a series of clichés relating to them specifically.
While stories of Nara Earth have survived much better, the Nara seal master has been mentioned occasionally in the scraps that still remain of the great playwright Kankuro's histories.
