Speak with Earthmender Duarn inside of Nespirah to activate her bio-defenses, then escape from Nespirah's body.
Thanks to you and the Captain, Nespirah has full control of her body... but most of the naga don't know this yet. Once we make our escape, she will activate her biological defenses and destroy the naga from within.
Make yourself ready... I will now tell Nespirah to begin the countdown.
