OK originally i was going to write this as if it was from an in-game book or something. but it just wasn't working so i just went for quick summery of my ideas

Of all the races of Marduk The wood Elves are the Most isolated. 

the other races question their existence.

Wood Elves don't have a country of origin instead they have multiple settlements in the many forest of Marduk (This Excludes the forest surrounding "Regnum Mortis")

They have the longest lifespan of all the races 

and are also known for there Xenophobic nature towards all races (Yes this includes the High-Elves)
