The Hangman's Mark appears as a dark, rope-like brand that wraps around the bearer's forearm in the shape of a loosened noose, with faint golden threads running through it like embers. The mark glows briefly with crimson light when the bearer achieves dominance or escapes elimination. It cannot be removed - only earned through survival. The brand feels warm to the touch, as if the rope that marked them still carries the heat of the frontier's judgment.

The Mark serves as both badge of survival and target - it identifies the bearer as proven worthy of remembrance, marking them as valuable targets for rivals seeking to claim a Mark-bearer's status for themselves. This creates eternal tension: the mark proves worth but also attracts those who would see the marked fall.
