Trebarnii BossBoss

The greatest leaders will make the hazardous climb into the branches of the nest trees to commune with the queens themselves. These bosses pass down a crude approximation of the queen’s language through the generations so that they can carry information from the ground and understand their wishes.

Some trebarnii will take the small kyatu as pets. The noisy kyatu can mimic the calls of the trebarnii and with careful training they can use their shrill cries to carry simple commands over long distances.
