Under-Hedge is like another world. A subterranean realm of cracked masonry covered in thin pale brambles. A labyrinth of damp marble walkways beside inky black waters like a Morlock Venice. In places overgrown railway lines lead to unknown quarters while above vaulted cielings give way to root clogged dirt.
Light is supplied by infrequent lanterns filled with blue flames, masses of fireflies or even odder light sources.
Under-Hedge is a unclaimed realm for the Night Market. The lowest members of the Freehold come year to scavenge. They risk the ire of the diminutive Underking, the hob lord of the devolved humanoids that haunt this realm. Rumors also circulate of ghosts and entrances to the underworld.
