“Questioner: Who are wanderers? Where do they come from?
Ra: I am Ra. Imagine, if you will, the sands of your shores. As countless as the grains of sand are the sources of intelligent infinity.
When a social memory complex (human being) has achieved its complete understanding of its desire, it may conclude that its desire is service to others with the distortion (characteristic which varies from the one Creator in its pure form)
towards reaching their hand, figuratively, to any entities who call for aid.
These entities whom you may call the Brothers and Sisters of sorrow move toward this calling of sorrow. These entities are from all reaches of the infinite creation and are bound together by the desire to serve in this distortion. 
Questioner: How many of them are incarnate on Earth now?
Ra: I am Ra. The number is approximate due to a heavy influx of those birthed at this time due to an intensive need to lighten the planetary vibration and thus aid in the harvest. The number approaches sixty-five million.
Questioner: Are most of these from the fourth-density? Or what density do they come from?
Ra: I am Ra. Few there are of fourth density. The largest number of wanderers, as you call them, are of the sixth density. The desire to serve must be distorted towards a great deal of purity of mind and what you may call foolhardiness or bravery.”
