A similar entry appears in the Wheel of Time Companion confirming the information available in the main story arc.
She is pale-haired and a year younger than Egwene. Despite having spent a year and a half in the Tower, Egwene thinks that she is still most definitely a girl.
As a prisoner in the Tower, Egwene comforts Coride when she is terrified after seeing a ghost walk into a wall and after she, Pedra, and some of the other novices in Pedra's class get lost in the Tower. Egwene tells her that the dead cannot harm the living, and that, besides, the ghosts were once initiates of the Tower, or servants who worked there, so the Tower was their home once, too. She tells Coride that the world is full of strange wonders, and that the Tower is full of wonders as well. Egwene thinks her words sound feeble, but Coride wipes her eyes and swears to never be frightened again.
