Upon taming it, Luna examines the strange creature's glowing horns. The elder thought they looked like blue jade, and Luna asked him to name this beast in his native tongue, Yu Jiao (玉角)

Selemene instructed Luna to travel to a distant Eastern town, where she was to be further tested in arts of the mounted warrior. Upon completion, Luna was bestowed an armor set and saw a strange beast unlike any other, unable to be tamed by warriors that captured it. Luna became its first master.
