Arachnolia

Queen of the Picodon Jungle, this huge spider used to be kind and gentle, but was turned in a ruthless cyborg by Malbec (standing as a testament to his cruelty) and now must be stopped at all costs. Unfortunately, there's no way to reverse her mechanization, so Istara ultimately mercy-kills her, stating that she'd rather have the queen dead and her spirit freed then allow her to live on as a soulless machine under Gandrake's control.
