Emma Iris Foster, or Kate Freeman, is Sophie Foster's foster mother in the Forbidden Cities. She is described to be a chubby brunette, and she does not like Sophie getting public attention. After Sophie left the Forbidden Cities, her memory of her past life was wiped out completely and she became Kate Freeman, living a brand new life without the slightest memory of Sophie. At the end of Lodestar, she was revealed to be taken by the Neverseen, to somewhere or someone called Nightfall.
In Everblaze, Keefe mistakes her initials (E.I.F) for the human spelling of the word 'elf' (E.L.F).
- SOPHIE FOSTER--(foster daughter)
Sophie's embryo had been implanted into Emma. Her belly button had turned pink and popped out like it would have if she were an elf. The night before Sophie left the Forbidden Cities, Emma seems to believe that Sophie was indeed her biological daughter, even though the truth was otherwise. She does not like Sophie getting public attention, and wants her to be normal like other children.
