Hù Yìn Shī

Hù Yìn Shī (護印師, Goinshi, "Seal Guardian") are the appointed stewards of the Shén Huì Mó Xiè (神誨魔械 Makai Shinkai, "Divinely-Instructed Magical Weapons"), mystical blades that were forged two hundred years ago to turn the tide of the War of the Fading Dusk. Unlike typical weapons, even the weakest of the Shén Huì Mó Xiè can be used to fight demons, a property believed to be bestowed to them by a now-legendary figure. However, many of them also possess powers that could prove cataclysmic in the wrong hands, necessitating that they be carefully guarded.

Sword Forging Shrine
For generations, members of the Dān clan were tasked with the protection of the Tiān Xíng Jiàn (Sword of Divine Retribution). The sword itself was kept under protective spells at the shrine while the hilt and guard were carried by separate Hù Yìn Shī. After the destruction of the Tiān Xíng Jiàn by Miè Tiān Hái and the freeing of the demon the sword once sealed, the clan now protects the Jié Huāng Jiàn (Absolute Phantom) that was used by Shāng Bù Huàn to banish the demon.

After the battle with Zhào Jūn Lín, Wàn Jūn Pò asked his men to join Dān Fěi and Juǎn Cán Yún as disciples of the Hù Yìn Shī to protect the future of the world.

Xiān Zhèn Fortress
The Hù Yìn Shī at Xiān Zhèn Fortress were the overseers of a wide collection of mystical swords, including the demon-tracking Zhòu Xiào Jiàn. When Lóu Zhèn Jiè sacked the fortress, Bó Yáng Hóu escaped with the Jué Jiāng Jiàn, Zhuàng Lí Jiàn, and Bā Shén Duàn Ji Dāo (collectively The Three Holy Relics). These were later given to Shāng Bù Huàn to seal in his Sorcerous Sword Index.
