One belief extant in the World of Darkness community is that the Heralds are the August Personage of Jade (from Kindred of the East) or perhaps their ministers.

The central evidence for this belief is that the same story is told in both books. Hunter: The Reckoning Storytellers Companion (in a section called The Great Cycle, pg.7-8) describes the origins of Hunters. In ages past, the gods weren't paying attention to earth and evil supernatural creatures emerged. The gods choose certain humans and imbued them with special powers to combat these creatures and lead humanity. These special humans later grew complacent and eventually evil themselves. Modern Hunters are new agents of heaven tasked with helping humanity through the coming apocalypse and into the new age.

This is the same story printed in Kindred of the East (in a section called the Coming of the Wan Xian, but continuing through Karmic Punishment, pg. 44-45). In this version, the "gods" are really the August Personage of Jade, who selected special humans and imbued them with the ability to use chi. They were tasked with destroying demons from the earth and to be responsible for humans in general. The Wan Xian eventually became complacent and corrupt, becoming evil beings themselves. There is no mention of the Hunters of the modern age.

I have not been able to locate anything either in the books themselves or other sources that conclusively says that these two are the same. This explanation therefore relies on circumstantial evidence.

There are many similar circumstantial links. For example, in Time of Judgment one of the potential endings for Kindred of the East involves Heaven waging a final war on vampires and the walking dead. A call-out box indicates that this would be an acceptable end to a Hunter game also. A second example is the story in chapter 6 The Walking Dead, in which a kuei-jin and hunter meet each other and seem to implicitly recognize their common linkage.
