Baby Stage Notes
This baby creature has dense, insulating fur, and cries loudly when it's too warm. It seems curious, but is too clumsy to move around on its own very well.
Juvenile Stage Notes
As it's matured, this mammalian creature has just gotten longer, and started to develop countershading patterns. It is carnivorous, and extremely energetic and playful. However, it becomes lethargic in the heat, and attempts to burrow to escape it.
Adult Stage Notes
Arthen are fast-moving, energetic creatures that become more hyperactive in the cold. Their antennae are extremely sensitive to changes in temperature, and they use this to sense prey in blizzard conditions. Kept cool enough, they are easily tamed if raised from a baby, though adults tend to be skittish and hyperactive. They respond well to simple training, and are highly food-motivated.
Arthen dig deep, cool burrows, and when found in areas without permafrost, aestivate during the warmer months in order to avoid the relative heat. Arthen that do not have sufficient space to dig become gloomy, but they do like to decorate their burrows with shiny rocks and other objects they come across. They only breed during the coldest parts of the year.
No two Arthen have quite the same shade of dark blaze down their spines, even within the same Chroma variant.
