My Beast is the shadow of my Muse, which is described in the Your Muse thread.
While my Muse is whimsical and indirect, dealing with it's mood swings (whether high or low) by gently asserting them, my Beast is it's exact opposite, direct, firm, and oppressive without ever needing to express itself with actions. While Freefall will display himself and his feelings in many different ways, often with little reasoning towards the method, Gale is ever present and always looming over me, always enforcing her influence on me, still and serene.
Resembling Freefall, her furred ears and tail and wings are not shaggy and soft, but glossy and neat. Her skin is either dark gray or enshrouded in shadow that shifts too subtly for my eyes to see, fur and feathers also a deep gray, black at the ends. Hair as dark as coal lays straight perfect down her back, a simple, unadorned brown cloth wrapped about her chest and hips all to keep her modest, feet bare. Her face is cruel but passive, dark eyebrows narrowing if she feels agitated, eyes pools of black ink, with only a hint of a silver crescent in them.
If ever I feel insecure of something, she is near me, watching me, crossing her arms and willing me to believe things I know aren't true. She is my jealousy, my possessiveness, and while if I upset Freefall he will huff or sulk or make a scene, Gale will simply step in front of me if I ignore her, burning holes in me with her eyes. It is very hard for to look away and ignore her poisonous influence. I can only ever shun her until she gives up, and those victories are very hollow, but she will simply return, another time. It is my constant struggle.
Where Freefall is wild and untamed in both appearance, personality and actions, Gale is a foreboding and oppressive stillness, in her appearance and behavior. Their very names are polar opposites, Freefall a gentle and careless drifting, like a leaf, and Gale a powerful and fearsome storm that will always seem still and harmless whenever I am not engulfed in it, watching the edge from afar... yet when I am swallowed by that storm, I find it hard to concentrate on anything outside of it.
Freefall is... admirable in his attempts to shoo her away or usher me off, but she scares him >.> easily. If I'm feeling like crap, and Gale does that to me, Freefall is more likely to just sit with me and be miserable.
