Christopher's intentions seem to have been mostly to use the latest writings of his father's that he could, and to keep as much internal consistency (and consistency with The Lord of the Rings) as possible, though he admitted that a complete consistency was impossible.
Christophers intentioner synes overvejende at have været at bruge det senest mulige af hans far skriftlige arbejde, han kunne bruge, og at opretholde så meget indre overensstemmelse (og overensstemmelse med Ringenes Herre) som overhovedet muligt, selvom han indrømmede, at fuldstændig overensstemmelse var umuligt.
