The Royal Exchange is the eastern of the two large trade districts in Silvermoon, connecting at its south-west corner with the Walk of Elders and at its north-west corner with Farstriders' Square. It features a bank, an auction house, and the Silvermoon City Inn, which also opens onto Murder Row. The jewelcrafting trainer can be found inside the large unnamed building forming the southern end of the Royal Exchange, in an alcove at its eastern end.
