Isha is the Aeldari Goddess of life, healing, fertility, and tears — the beloved mother-goddess of her people in the age before the Fall. Gentle and compassionate where so many of her kin were cruel or violent, Isha was cherished by mortal and god alike, the giver of life and the easer of suffering. In the oldest myths she defied the will of other gods to bring hope and knowledge to the Aeldari, and for her compassion she was beloved above all.
When Slaanesh rose in the cataclysm of the Fall and devoured the Aeldari pantheon, Isha's fate took a stranger turn than most. Grimdark legend tells that Nurgle, the Plague God, seized the goddess of life and bore her into his festering garden, where he holds her captive still — forcing her to sample each new plague he brews, that he might read her agony and gauge his contagions' potency.
Yet even a prisoner of the Plague Lord finds ways to resist. It is whispered that Isha weeps for her lost children and murmurs the cures to Nurgle's diseases into the world when the Grandfather is not listening — a mother's defiance enduring even in the depths of decay. To the surviving Aeldari, Isha remains a symbol of life, mercy, and the tender hope that even in the grim darkness of the galaxy, compassion has not wholly perished, and that somewhere still, a mother grieves for her scattered kin.
