[ID: two flags with seven stripes, with swooping shapes at the bottom left and top right corners, which emerge from the bottom and top stripe respectively and end just over two-thirds of the way up and down the flag respectively. The colors, in order, are dark blue, muted purple, muted blue, very dark blue, muted blue, muted purple and dark blue. Their bottom left swoop gradiate from dark blue at the bottom stripe to green at the tips and the top right swoop gradiate from dark blue at the top stripe to pink at the tips. In the first flag, in the center is a light blue symbol that looks like a magic wand. It's made up of a straight line with a symmetrical star with eight sharp points and a dot in the middle. There’s a comet with a circle body with its tail wrapping around down the handle of the wand. At the same end as the star, one on either side of the line and not quite touching the line itself, are small bird wing shapes. The magic wand is slightly tilted to the right. The third image is the magic wand by itself with a transparent background. End id.]
