Canterlot Wedding1

Despite the injuries sustained during the Changeling Invasion of Canterlot, Captain Greyline was able to evacuate a little over twenty civilians from the city away, fighting off a transformed changeling (as seen in the art depicted here) away in order to help buy them time to flee. He survived the fight with several major injuries, while the changeling (who is now known as Calypter) was forced to flee. The two would eventually meet again during the Canterlot Summit a year after Thorax began his rule over the Changeling Kingdom (on much less hostile terms, of course.)
