These docile spiders fit in the palm of one’s hand and are very soft. They are always of two colors whose hues vary from one specimen to another: one kosmima can be bright blue and soft pink, and another stark purple and shining coral. They are terricoles, and in the absence of ground soft enough to dig, they settle in a hollow within a rock or root where they make themselves comfortable by covering the walls with slightly sticky silk. This cozy dwelling is their hiding spot-from which they spring forth in ambush-as well as their brooding nest.

The drow are particularly fond of kosmimae, which they carry in their hair or on their shoulders like living ornaments. These creatures are known to be loyal and capable of recognizing a humanoid’s voice and features, and so they are often gifted or exchanged as tokens of deep affection. They can be trained to carry messages rolled into a small metal tube strapped to their back, which they’ll take to a familiar person in a location that they have previously been shown, making them handy helpers for both lovers and spies!
