I didn't see a thread for brainstorming on good ways to intigrate the new races in 4E, so I figured we could use one.

Tieflings: I think the simplest way to bring these guys in is to have them be descendents of powerful Awnshaghen or other corrupt bloodlines. It plays into the whole "Sins of the father, not you." schtick of the Tieflings, while tieing them to Birthright's whole bloodline theme. Personally, I don't mind there being devils in Birthright, they add to the midevial Eurasia feel more than they detract from it, but I figure keeping the option loose is best.

Dragonborn: These guys were tricky, but I think you'll like this: They're what's left of the free Masteans. The Serpent lied to the world about just what happened to his people; the last Masteans were herded to the Serpent's island where he preformed foul experiments on their blood in an attempt to breed a race of super-soldiers with which it would conquer the world. They were released early when one of the legendary true dragons of Cerilia learned that the Serpent slew one of its siblings to power his vile experiment and attacked the Serpent's island; the majority of Dragonborn reject the Serpent and everything the awnshaeghen stands for, though some do believe that it is their destiny to rule Cerilia as a superior, hand crafted species.

Eladrin: For me, these fellas were the hardest. Cerilia's elves were allready pretty darn Eladrin, after all. Then I remembered Tuar Anwyn, and it came to me: The Eladrin were groups of elves who, rather than submit to a human-dominated Cerilia, journeyed into the Shadow World/Shadowfell, hoping to force a perminant path to the Feywild. It didn't work out. Hundreds of harrowing years later, the Eladrin returned to Cerilia, changed on a spiritual level by their journey; some renounced their bitterness, joining their forgiving elven cousins and even coming to live in some of the more civilized human realms. Others claim to be of finer stock than any current elf ruler, muttering about dirt-blooded commoners and trying to sieze power, if not outright rulership, of their domains; Lullibright was the first to fall, but may well not be the last. Finally, a group of Eladrin are rumored to have sworn allegiance to a twisted awnshaeghen known only as 'The Demon Queen of Spiders', a bitter creature who's creed of hate against any race that isn't Eladrin has human, goblin, dwarf and elf telling stories of nightmarish raids by these 'dark elves', these 'Drow'.

The return of the Eladrin could mean a return to greatness for the elven nations of Cerilia...or the final fall of those proud peoples. Only time will tell.
