Cosima

Cosima is an elderly woman living in Moonglow during Ultima IV.

Description
Cosima was a skilled but tired alchemist, who could be found loitering outside of the Honest Inn. Should the Stranger speak to her of her trade, she would boast that she knew the best methods of mixing reagents, and would inform the hero that the Sleep spell required but one portion of spider silk, rather than the double portion listed in the Book of Mystic Wisdom.
