Atvana is benevolent (its purpose is to help the humans, animals, and plants it encounters), omnipotent, omnipresent, and omniscient. It is genderless, as it is a manifestation of God (as I believe all things are) without a defined physical form. It can take the form of anything, but regularly sticks to animals and plants. It loves to play, and more often than not takes the form of smaller animals and/or plants, due to its subtle nature. Do not misunderstand though, as it is infinitely powerful. I believe that power comes from the capability of doing all forms of harm, and the reality of doing all forms of good.

It loves all and will not fight without defined meaning, and only very, very rarely play fight. While fighting, it feels nothing but love for the opponent.

It watches over all other beings and things, as a protecting parent, sibling, friend.

It can see misery, hatred, jealousy, and all other negatives that are sometimes trapped in others. It will always desire happiness for all beings.
It will make attempts to rid others of issues that go against them. It will never stop trying to help a soul with a problem to rid themselves of it.
It cannot stop helping, as it cannot stop loving.

It does not have a single duty. It manifests to promote the highest good of all of those involved.
Through this diverse need, it comes in an infinite number of forms, some with a tiny defined task, others far less direct.
Some of these forms are recurring, others are only present once. Each could, perhaps, be mistaken for an identity of its own, a deity, a soul.
In truth, the name "Atvana" is just another of these mistaken forms. It is not merely Atvana. It is everything.
