Lightning Blade, 2nd Commander of the Solar Stallions, now retired, he's not old, nor injured, he saw too much death. He wandered around Canterlot, hoping to find a reason for his life, and when he thought his destiny was to rot, his friend Emerald Spark got him back to the army, there, his adventure begins, to the path of the Lunar Stallions.
(I currently don't have a friend who draws fan-art for me, since it's holiday here in Malaysia, no one wants to draw, so I got a random image from google, hope you guys don't mind.)
