Journey of Embers
The Elf and Eladrin races have a shared belief of where their races originated from. They believe that there was a great being of high magical prowess. This being felt limited by his mortal form and cast if off. This form would be the origin of the elves and the magical form left would give birth to the Eladrin.
Elves unsurprisingly excel in martial prowess. The tend to focus on speed and maneuverability. They are not the sturdiest of the races that focus on martial strength but they are the hardest to catch.
Although they focus mostly on martial combat they are not tied to it. It is not unheard of to find elves that train in magic. Mostly they focus on primal magic but other forms can be seen in their ranks.
