Kiken

Famine was a maho-tanto created by Hantei Jama, who would be later known as the infamious Iuchiban, during his time in the Imperial Palace.

Abilities
The knife was semi-sentient and it could become lost or overlooked by those it did not like. The tanto would try to make its servant of anyone who wielded it, seeking any "pure" individual to be murdered.

Scorpion Coup
The knife was found by Ozuki, a servant of the Palace, years before the Scorpion Coup. When Ozuki's family was slaughtered by the Scorpion he slipped to madness, and wielded Kiken. The blade managed to take its wielder's will and Ozuki began to murder any honorable people he found in his way.
