Fulu (foo-loo)

The talisman paper, itself, is called lingfu. While the fu and lu characters each connote a different aspect of the script used on the talisman. The fu part of the script are considered to be the actual instructions of the spell for the magic to be focused through. Whether that's the magic of the Tao, or instructions to the practitioner's spirit companion, or the wider spirits themselves, is up to the individual practitioner. While the lu part of the script is considered to be the authoritative part which compels the magic to act as instructed. This is typically a small pedigree of the practitioner with several generations of their teachers, along with the skills the practitioner possesses.

Fulu have long been used by the mystical occupations of the empire since the means of paper production were discovered. In the earliest days, they were used by the ancient priests and shamans of the tribes and clans to offer up prayers to the deities. As it was thought that a physical representation of the prayer held more significance than a mere thought. Over time, these came to used as part of rituals, themselves, to speed up certain magical rites such as exorcisms. 
In these ancient times, the script used on the talismans were simple and easily read. Over time, however, they became largely, and deliberately, cryptic as a sign of their divine origins. This Talismanic Script eventually came to be the proper way of writing them and gained a sort of perceived authority and efficacy when used.
Once the Eight Thunders and their Modaoshi came onto the scene, they began utilizing the fulu to transcribe their own ritualized spells in order to cast their magics quickly and efficiently. The ritualized spells and the fulu became so commonplace, in fact, that it is the Madoshi's primary means of casting their magic. The fulu have largely fallen out of favor with the other mystical occupations outside of certain, more commonplace, rites such as exorcisms, sealings, or summonings.

Fulu are used to a greater or lesser extent amongst all of the mystical practitioners. They are used by Kamunushi and Souryo priests, as well as many hedge-witches, lay priests, and sorcerers. Over time, these simple talismans even inspired the ofuda used by the Daiingo peoples in their mystic pursuits.
