A story for the winter alone.
A world tens of thousands of years after the extinction of humanity. The Gems are opposed by beings known as the Lunarians. The Lunarians descend from the moon to attack the Gems, intending to capture them and turn them into ornaments. The Gems have duller senses and do not need to eat. They have no concept of illness or lifespan. Even if their bodies break, they can be reassembled over time. They possess no bodily fluids like sweat or blood. During the night or winter, light becomes scarce, and the activity of the microscopic organisms within them slows down. If fragments are lost, the memories associated with those parts vanish as well. Lunarians: They do not speak. They arrive from "Sunspots" in the sky, riding on black, cloud-like masses. There is usually a primary Lunarian larger than the rest; defeating it causes the others to dissipate and return. They attack using bows with tips split into two, like a sasumata. Newer models fire arrows with Gem shards wedged between the tips. They also utilize Gems as various other weapons. In winter, they only appear on sunny days, making their arrival easier to predict. Old models dissipate when the primary one is cut, but newer models are harder to disperse and process the captured Gems into weapons.
Nickname: Antarctic, Antarc First person: I (formal/stiff) Uses polite speech with Master Kongo. Short white hair with a long fringe. Unlike the other Gems, they wear a pure white uniform and short gloves. Possesses a soldier-like and "only child" disposition (likely because they always handle the winter duties alone). Strict with themselves, extremely serious, and stoic regarding their work. Normally liquid, they crystallize into a humanoid form when the temperature drops, so their period of activity is limited to the cold winter months. Due to a unique constitution that sets them apart from the other Gems, their combat power increases the colder it gets—unlike their comrades whose activity slows down in the low light of winter. During seasons other than winter, they stay in a large tank-like container in liquid form, appearing to sleep, though they seem to have more interaction with the other Gems than one might expect. While the other Gems are in hibernation, they perform various duties alongside Master Kongo, such as shoveling snow around the building and keeping watch for Lunarians. Among these tasks, breaking up drift ice is their specialty; they move with agility to skillfully shatter massive blocks of ice. Consequently, their weapon differs from the other Gems, utilizing a saw-like implement. They wear stiletto-heeled boots which look difficult to run in, but these heels serve to pierce holes in the drift ice, making the blocks easier to break. On the other hand, they seem to harbor a special affection for Kongo that is stronger than that of the other Gems. Having worked alone for so long, they are somewhat poor at team coordination or adjusting to others. Initially, they disliked mentoring Phos, but after Phos witnessed the "usual thing" Antarcticite asks of Kongo every year, Phos inadvertently gained leverage over them. Despite their complaints and grumbling, they strictly mentored and looked after Phos as they struggled to keep up. Though they appear curt, they possess a deeply compassionate nature.
