Udinaas had a vision in which Menandore and Sukul dragged an unconscious Sheltatha Lore between them and had a conversation with Osserc. It also showed that shortly after Scabandari Bloodeye betrayed Silchas Ruin, and was in turn defeated by Mael and Kilmandaros, Menandore and Sukul conspired to defeat Sheltatha. They then interred her in the Azath House in Lether where Silchas Ruin was buried.
Udinaas meets Rud Elalle and realises that he young boy is Menandore's son and that he, Udinaas, must have fathered Rud when she raped him.
She was sister to Sukul Ankhadu and cousin to Sheltatha Lore. The three had a history of allying, betraying, and assaulting each other. Menandore was described as a daughter of Tiam and Osserc however, the former was likely to have been mother only in the sense of birthing Menandore's Soletaken aspect. (Blood ties are difficult to establish with certainty as female Soletaken descendants of Tiam seemed to customarily describe each other as sisters/half-sisters).
Menandore was named as the bastard daughter of Infayen Menand in Fall of Light. As Infayen did not want the child, Menandore was raised by another family.
