Char Witness manifests as a small iron brand shaped like a stylized flame, its surface perpetually warm to the touch and etched with what appears to be ash but cannot be wiped away. When held to light, the brand reveals tiny figures frozen mid-stride - settlers caught in the moment of transformation, their forms half-emerged from the darkness of the char. The brand cannot be truly destroyed, only transferred through completion or abandonment of the journey. It pulses with a dim glow during crisis moments and changes appearance based on the bearer's recent performance in the wagon column.

Char Witness marks those who have survived the crucible and serves as a reminder that transformation leaves permanent marks - the bearer carries proof that they were tested by fire and emerged as carbon rather than ash. It distinguishes the Homesteader from the Drifter through the visible evidence of transformation, connecting all four leagues as the measure of who truly endured.
