The Guiding Light has no official name. Although not possessive of a physical appearance (until you die and see her), the Guiding Light serves a purpose of helping and communicating with the human with its prominent glow, the presence it sparks, and its accurate advice for each hostile entity in various ways. An angel. She has light blue, glowing clothes, and has a yellowish-white halo over her head. Kind of ticklish. Will give you the chance to revive or stay. 13 years old. Same for you.
