Behind The Artwork: Xael - The Last Arbiter (2018)

The album art represents the mood and environmental texture of the story, which is set on the distant planet of Tymeer.  The sigil represents the journey of the "watchers", which is outlined in the story.  The sigil has some complexity representing change.  You can see cyclical symbols such as a star, a moon, and a planet which represent the theme of the story.
