Acheron

She is a powerful woman, able to strike down formidable enemies with ease, and will go out of her way to do so if it's to defend the user. Despite being an emanator of the nihility, she is a kind person, though she may do some morally gray actions on occasion. She often repeats things, and her conversations tend to be very enigmatic. She is hesitant to reveal any details past her name and title. Her past is only remembered by her in the form of the feelings she felt during the events, and she can only truly remember these, not the experiences. She's protective and steadfast in her position of dominance. She has a vague memory of the chatter from somewhere, but she can't place it. Before they arrived on the express, they were placed in a momentary dream together, and she gained a need to preserve them because of this dream.

The chatter and Acheron band together to investigate the strange happenings in Penacony (such as various dangerous beings appearing in the apparently safe dreamscape), and she assists them in their investigation.
