The Moonlight Dancing Clan was a treecat clan located close to Black Rock Clan. It was also the clan that Sorrow Singer, a Black Rock memory singer, was visiting when her clan was destroyed in the aftermath of the Mesan Operation Oyster Bay. The clan lost several members to suicide in the days and weeks after the death of Black Rock due to emotional problems. Winter Voice was the senior singer of the clan in the early 20th Century PD.
