The Arrival of Galeem

When the light first appeared, the shield turned dark to prevent anyone from getting blinded. Flurry ordered mirrors to be set up in case any light from this entity managed to break through. Everyone was also required to wear sunglasses because even the shield could not filter all of the light. Eventually, the entity itself managed to teleport through the shield and travelled to Canterlot. The Young Six tried to guard the doors to the throne room, but the light was too much for them and they were left blinded and dizzy. Upon entering the throne room, the entity revealed its actual form. It was a featureless figure with rainbow colored wings. Its body was a pure white color.
