The shaman pauses before she recounts her entire vision. She feels ants crawling through her scalp down to her neck, spreading throughout her back. It has been hundreds of years since she has had this feeling showering over her - the feeling of her goddess's presence, Karta.

Seeing such an opportunity arise, Lin and Ian become attentive to what she has to say since she seems awfully shaken by it.
