The elf population is declining, and there are already several homes that will be without elves this Christmas. Things can't move fast enough—we need more elves! But how do we get them?

Pyrus, Kandis, and Gyldengrød are joined by Fix and Fumle, and together they set about establishing an elf school in the National Archives.
