Moki and the Erased Ones

Moki is the only blue-haired Y'nari in a repressive culture that fetishizes racial purity. Educated in secret about a world before Imperial rule, Moki is discovered by the Inquisition before she can complete her heretical studies. She is forced to flee into the mountains where she is captured by slavers who are using a workforce called the Erased Ones to exhume an ancient structure entombed beneath the rock.
