Orfeo's Path
Orfeo's Path is magical feat of Trod-craft.
Overview

A feat of portable trodwork, Orfeo's Path can be called into being anywhere by any changeling who has learned the proper techniques. Essentially, the would-be trodwalker scatters eggshells on the ground before them and begins walking, taking care not to step down too hard and crush the fragile shells. This procedure requires a certain degree of concentration and dexterity; however, once the trail has been forged in this way, the trodwalker's companions may follow without fear of breaking the shells (or magic). For arcane dream-logic reasons, the trail of shells partakes in the nature of the Silver Path, and whoever walks it need not fear unprovoked attacks by nightmares.
On the other hand, if the trodwalker themself breaks the eggshells underfoot, the trod comes to a dead end. The Dreaming seems to ensure that this failure strands the trodwalker in some dangerous situation (lost in a snowstorm, poised on the edge of a sheer cliff, menaced by cannibal monsters), but the Path can again be called back into existence... once the immediate danger is dealt with.
