SoulWorker Wiki

The Trader Alliance or Stair Merchant Union is a group of merchants dedicated to selling general goods after the Great Void. The group was created to help provide general goods to public due to the prevalence of price gouging. Like the Starry Forest League, the Trader Alliance has a keen interest about studying new technologies. Members of the Trader Alliance follow the player SoulWorker as a means to make profit.


They are main rocket supplier for NED Company. After learning that NED Company allied with the Bashai, the Trader Alliance voids all current contracts with them. The Trader Alliance works together with the Starry Forest League to build the Abyss Lounge combat system.
