Sulfur Moon

Sulfur was the daughter of the lead pair, which gave her some level of authority amongst the pack, although for the most part she earned that respect on her own. She was told she was like her ancestor, one of the founders of the pack, Slate, with her ability to listen and advise others, always lending an ear. Although her eyes were startling at first to most, they quickly became soothing for other wolves, their soft glow almost reassuring as she would quietly listen and support her pack mates.
Her sister Lichen, born a year before Sulfur, enjoyed teaching her, they took after their father, Lion, and were both very capable stalkers, among the best in the pack at hunting down prey.

She wandered a bit when she was young, pairing up with a wolf from another pack for her first heat before returning home to have and raise her pups. She had gone north, into the tundras, and it showed in her pups, blue in their coats and a daughter with strange eyes, but the pack had a history of taking in frost touched wolves and so had no qualms with it.
Sulfur overheard her daughter Silver being told many times about one of the first herbalists in the pack, Chalcedony, who had striking clear blue eyes. Sulfur had heard those stories herself as a pup, how their different looks might be a gift.

When Quiet Dove joined the pack, Sulfur was immediately drawn to him. He had a charm, a warm and welcoming aura that made her want to be around him. Things were busy and chaotic but she found his presence and his confident leadership calming. After her parents died, Dove naturally took on a role like they had, arranging the vigil and burial of her mother, Lark, and making sure things kept running smoothly while Sulfur and Lichen decided between the two of them who the next leader would be.
Lichen encouraged Sulfur to take that role, she knew the pack better than her sister, the way she could weave her way through the pack, speaking to each wolf, listening to their concerns and easing them, when a mother wolf was concerned about a nearby fox den Sulfur would set up a patrol to chase them out, or when she noticed a wolf looking thin she would increase hunting patrols. Lichen called her "the heart of the pack", and said that she was the obvious choice.

Dove asked her on a walk one night, and she agreed. They roamed the territory in silence for a while, before she broke it, and asked him to be her mate. He laughed, and told her that's why he wanted to go on the walk in the first place. Where Sulfur could calm her pack mates, Dove could calm her, and he was still taking on leadership, it only made sense for them to lead together, like her parents had done.
They had a litter of pups soon after. One of her pups came out green, like her mother had been, but even more strange, her own fur had started to shift and change color. Her teeth had grown too, she didn't notice at first, but soon it was blatant.
