You'll want a moniker for me, won't you? Words and names are not explicitly necessary to process the world within oneself, but they are important when conveying it to others.
I don't have one of those, not as I am now. Not anymore. Others have found that problematic, so they say things like nameless, ethereal and "whatever." They describe my qualities, if poorly, but not who I am.
As a being who possess free will, or as much of it as one can truly possess within this universe, who I am is the sum of my actions. I am what I do, and what I do is wait. For you, for the Earth, for everything - I wait. On and on into forever, I wait and I wait, so that is who I am.
I am One Who Waits.
