This is a Mandriva icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,600 icons, all in the same style and quality.
The icon is shaped like a 5 pointed star with a crescent moon shaped facing it. The crescent shape starts from the left side and curves around to the bottom center. The upper right point of the star has a smaller X shape at the point of it that resembles a twinkle.
