Name means: moon-prayer (full name in Standard Méri: Lunapéra)
Pérha enters the Four Lights cycle as a herder‑woman from the drowned village of Salúti, a village beside the Sweet Sea. As a young woman she travelled to the uplands of the River Néra, the Black River. Skilled in healing and animal husbandry, with an adventurous streak, her story is told in the novel In the Day of the Flood.
Pérha is the milk-mother of Deghóm and the blood-mother of Láko. The lay of Pérha became part of the Four Lights song cycle, the tales of the great deeds of the Tuméra, sung in the hills above the Sea for many generations. Hers was the quiet resilience of a strong mother and milk-mother, but she became a leader of her people.
Pérha agreed to be interviewed by Stephen Thomas after her tale was told in In the Day of the Flood. During the interview she revealed an earlier part of her story in which she first met her husband and found her way upriver to the hill country where Deghóm was born.
