Isha

Isha is the Eldar goddess of fertility, life and growth. Though long thought to be destroyed by Slaanesh, she was in fact taken captive by the Dark Prince. Nurgle took pity on her and waged war against Slaanesh to 'rescue' her. Nurgle took her back to his domain and keeps Isha caged in his workshop, testing his latest plagues and diseases on her. Isha can cure herself of these afflictions, but Nurgle gets an idea of their potency anyway. Isha whispers the cures to these new diseases into the universe so that mortals might know them.
