The male packbison had collapsed at one point, and some of his supplies had to be transferred to the younger female. Raki could barely stay on his feet, and his exhaustion had carried through the bond to Kyreia herself, whose lips were dry and chapped and whose eyes struggled to stay open.

He snorted, put his nose to the ground and lumbered off at great speed, tugging the other two bison with him. Kyreia gripped the saddle and leaned forward, and Raki chased after them, snarling desperately in threat.
