The Arryn House logo is composed of a crescent moon on the left side that's empty part is on the right. There is a bird then on the right side flying into the little slot of the crescent moon.
This is a Arryn House 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 13,700 icons, all in the same style and quality.
