I am about to head off to rescue Imoen and was wondering, if I dismiss Melora where does she go? She mentions look for her in the shadows, but I did not find her anywhere I looked (Slums/CC, original spot in W. Promenade, Graveyard, etc).

Do I miss out on any of her quest if I do not take her along? She seems like the natural party member to drop since I will pick Imoen back up.

Thanks.

Unfortunately, you will never find her. Her personal quest will started if you will go to Candlekeep area. Please go to Quest and Walkthrough section and read about this.
