Return of the Elflings

It is said the Elflings, a half Elf half beast species, only appear in dire need. It has been 12 centuries since the last known Elfling existed. Though humans, Elves, and the Otherlings do not fully understand eachother anymore, and the Final War forgotten, the Freelands have been at peace since the Dark Ones have been defeated. Now a young Dragon Elfling appears and the Elves haven't a clue why. The Elfling is unttrained, and only few still live who remember the Elflings enough to train them, but can it come to it's powers in time to save the Freelands from what can only be another attempt by the Dark Ones to enslave and destroy all which has become once more?
