Riva Coppermill ( 394 AC - ? AC) was female Dwarf merchant in Hylo. In 421 AC, Anta made a pilgrimage to the Citadel of Light. She was a believer in the One God. She visited the Citadel of Light to see where Mina grew up. She was almost attacked for voicing her beliefs in the Cozy Hearth, but Iryl Songbrook stopped the crowd. Iryl then told Riva not to talk about the One God any longer. Riva decided not to stay there that evening.
