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.
