Who is Ione Saldana from The Neutronium Alchemist Consolidation and what is their importance?

The Lord of Ruin, rule of the habitat Tranquility, is a young woman of keen intelligence and playful spirit. Affinity linked to the habitat, she can observe anything that occurs on Tranquility. She is related by blood to the ruling family of the Kulu empire, but her existence is not acknowledged on Kulu because of a longstanding taboo against affinity and Edenism that her relationship with Tranquility violates. Like the previous Lords of Ruin, she believes that the study of the nearby Laymil orbital ruins is of supreme importance. She is one of Joshua Calvert's lovers and her first offspring is conceived using his DNA.
