- "The Kith are as good as dead and you know it."
- — Temper Fray to Damocles Creed, the latter being the leader of one branch of The Church of the Faceless
Kith are mortals/sorcerers who have failed to become a Child of the Faceless Ones during a process called activation. When a Faceless One takes a human as a faceless vessel, the human is usually burnt out before they can become of use. But, if a faceless one leaves the body before it can be disintegrated, a tiny bit of faceless ones DNA can fuse to the body's DNA. This mage or mortal‘s descendants will also have this DNA.
It can be activated by a process known only by the worshipers of the faceless ones, but if the DNA in the subject is not strong enough, their mind will be wiped and their facial features will melt off. That is when they are a Kith. But, if the DNA is strong enough they will become a child of the faceless ones. This hybrid would be theoretically be capable of calling the faceless ones from their own dimension.
When Temper meets Creed the man behind the creation of the Kith, they begin talk of The Religious Freedoms Act. They speak of how the act enables all religions to worship how they please, Temper adding that the Church of the Faceless are the only religious order to advocate human sacrifice. Creed denies this but Temper claims that the Kith are "as good as dead," and also claims that he was "next on the list to be sacrificed." Creed speaks of how the Kith will be the first in line to meet the Faceless Ones upon their return.
In Bedlam, Dusk tells Valkyrie Cain about how once, many years before, he was extremely hungry and came across a building holding, unbeknownst to him, Kith. Dusk tastes their blood before not bothering due to the "funny taste." He reveals that he tasted the same thing in Valkyrie's blood, except "Theirs (the kith's) was the echo. Yours (Valkyrie's) was the song."
