Aaru is a mysterious creature from outer space. They have taken a form of a canine figure, with reptilian features and an odd, fluffy body covered in thick fur.

They have the ability to speak in any language, but only do so telepathically; never opening their mouth to speak, in a way.

Aaru spends most of their time exploring worlds and cultures, but acts more as a silent observer more than anything. They prefer being unseen by strangers, observing people and animals' behaviors.

They also love napping and eating anything that could fit in their mouth. They also consider themselves as a royalty, and have a fascination for golden and fancy stuff. They hoard some of it in their habitats.

They're a passive-aggressive, loner kind of being.

Overall, Aaru is a creature without much information. Their history and origin are covered in mystery, and no one's ever gotten them to tell their story yet.
