Sigyn is the mythological Loki's wife. Her character is derived from the stories I found of her.
Sigyn was her name; she was tall, lithe, elvish of face, and shockingly beautiful. She wore but only the finest animal furs upon her shoulder and the softest silk upon her breast. Her hair was copper and curled to the nape of her back. Her eyebrows arched gracefully, like her dainty nose and like her nearly full lips that caressed her pale face. Her cheekbones were high and soft, like her jaw. Her eyes were half-almond shaped; they held pale green orbs within them. They were gentle eyes; they didn't inflict fear on sight. No, they were the eyes of a kind woman – they were eyes that agreed with you.
Sigyn's looks were enviable. She would be the talk of the land if she happened to make an appearance. Women would beg at her feet for just a small share of her beauty. Men would grab hungrily at her shoulders, legs, breasts; she was irresistible to all.
And who would be suitable for such a stunning woman? Would it be a king of all the lands? A man with broad shoulders, square jaw and a rippling aura about him? Or perhaps, if she so chose, a petite woman with large hips and golden hair thrown over her shoulder?
For Sigyn, her partner was similar to her: Tall, lithe, elvish of face, and shockingly beautiful. They shared many qualities, both physical and spiritual. However, he was more elevated in the tricky side of it all; he was, of course, the greatest prankster to have ever lived.
He was Loki Laufeyson, the God of Mischief. And with his seemingly evil hands, he lay them upon her cheek with the lightest touch and let out the softest breath. He would build and destroy things with the very same hands, but with Sigyn, he treated her like gold.
She was his wife, and he was her husband. They were united by a unique bond neither of them had experienced prior to their relationship, and it was rather impressive. She kept him safe from harm in trying situations. He protected her from the evils of the outside world. Even when he was away, Loki ensured her safety. A cat couldn't even glance her way without Loki noticing.
So, surely, Sigyn would be safe, at all costs. Would she not?
It was often Loki found himself trapped within his own study, up to his eyes in books about new spells to keep away intruders, new magical back-up plants to the back-up plans of the back-up plans, if the back-up to the back-up of the back-up to the back-up didn't work well enough.
It was also often he questioned himself for being so precarious. Did Sigyn feel crushed beneath Loki's protection? Did she ever feel isolated and alone?
Fortunately for him, the answer was no. Even though his safe-guarding put a damper on Sigyn's life, she actually had quite the amount of free-range around Asgard.
She could be seen strolling the gardens and conversing with the beautiful children. Sometimes, if an on-looker was lucky, she could be found painting and singing in the small garden over-looking a crystal lake behind the wooden house Loki had built for her. She was safe and happy.
Sigyn's day began early; she woke with the light of the morning. There were days Loki would rise beside her, and days he wouldn't even be present in Asgard. When he did happen to be there, they would sit together in silence at a crooked wooden table and eat pastries for their first meal of the day.
Afterwards, Sigyn would bathe in the light outside; she would wear a loose-fitting purple gown that washed over her like water; and, Loki would rest beside her, eyes feasting upon her beauty.
They enjoyed talking with one another. Sigyn would share tales of her childhood or stories she'd heard from the women around the towns; Loki would illustrate beautiful stories of his endeavors. He'd use his hands a lot when he spoke to her; he'd shoot them in the air to describe a flying beast, or he'd shoot them quickly forward to elucidate some sort of magical spell he'd cast. Sigyn loved hearing his stories.
Later in the day they would stroll through Asgard together, until they would eventually part and the two would continue their lives as if they didn't know each other.
Sigyn would make her way to the grand library and read in solitude with Loki's adopted mother, Frigga. Loki would find a god to torment and have his fun.
Sigyn was a happy woman. She was devoted to her husband, and was ready to sacrifice herself for him if the situation presented itself. But, until then, she would continue to live her life and expand her knowledge of the nine realms.
