Scavenger Merchant

Location
The Scavenger Merchant room is a special room that can be found in Garbage Wastes, Shaded Citadel, Sky Islands, or Subterranean that's decorated with lanterns on long pikes and various Scavenger graffiti. Typically, a Scavenger will stick around in this room unless scared off who holds a plethora of items. This Scavenger is known as the Scavenger Merchant, the namesake of the room.

Scavenger Merchant rooms are usually a hotspot for nomadic Scavenger groups. The creature dens in this rooms are used by them often, and groups tend to stay near these rooms. This usually means Scavenger Merchant rooms have no items on the ground as they're all stripped away by the nomadic Scavengers.

NPC
The Scavenger Merchant is a Scavenger who is just like any other, defined by its behavior. Scavenger Merchants will stay inside the Merchant room unless scared away by a predator or the player character if Scavenger reputation is too low. They will fight back if not able to get away. Scavenger Merchants usually are fully stocked with lanterns (not in Sky Islands), mushrooms, grenades, and most commonly, spears or explosive spears. They will be more accepting toward the player character than other Scavengers, being less likely to attack or run away, but will still do so if your reputation is too low.

Trading
Scavenger Merchants value items equally as much as all other Scavengers. The items they'll prefer to drop over other items are the same as other Scavengers as well. The higher your reputation with the Scavengers in the region the Merchant is found in, the more items you will receive through trading. For example, at a neutral reputation, giving a Lantern might only give you a single spear, or nothing at all, while being high in reputation will net you more for your trade. This is the same principle with every other Scavenger.
