Now I will continue with my zodiac rubber drones.

This is the sixth-born of the zodiac animals. Its name is Borkur.
The passage where it is created in the holy book is as follows:

"And THE CREATOR made a sixth creature, fur decorated its body, and it flew down like a robe. With its horns it carried the fruits of the earth and it was a messenger of spring in a world of winter and its nose knew all herbs and flowers and imposant was it's appearance.
And THE CREATOR saw his opus finished and he saw, that it had become good, and he called the creature Borkur and he called it yak and it was the first cattle of the forests and it was a creature of earth and it carried a piece of water."

After the twelve big animals have been banished to the night sky, they conspire to obsess the twelve children of the first fleshly people. Borkur chooses to take control over the body of Hiranyata, the father of the nations of Habatara (India), Bodrask (Tibet) and Mulanbatar (Mongolia).

"Borkur, the yak, committed itself to Hiranyata, for he made delicious food and he made much food out of the fruits of the trees like those from the horns of the yak who liked to eat."

Several thousand years pass after this until the time in which the novel takes place. Of the twelve knights of the stars who have to protect Silas, Broku is the one who is Hiranyata's heir and is born under the sign of Borkur. He has all abilities of both of them and his mission is to purify Borkurs soul by her pilgrimage with Silas.

But in an alternate universe, the Knights can't purify the big animals, but are corrupted by Kaxeiko and transformed into anthropomorphic latex versions of their animals. As a rubberized servant of Kaxeiko like in this picture, Hiranyata/Broku/Borkur is made completely of latex and has no other wish than to help the demon of lust to transform the whole world into gummi with her sticky goo.
