Yes, mentioned in Marty's Book III.

Others, not so much.
Hubbard possibly came up with some of this stuff by reading ancient gnostic materials.
For more, just google: gnostic prison planet
Couple of typical quotes you'll run across:
"The earth, for the Gnostics, was a prison-planet ruled by an evil tyrant. The soul would continue
to reincarnate in this insufferable vale of tears until the power of Ialdabaoth and his evil angels
(the "archons" which encircle the earth) could be broken."
"So the problem is simple, and one begins to understand how the Gnostics saw it: man, then, is
a lifelong exile on a planet which is a prison for all mankind; he lives in a body which is a prison
for the soul; he is the autochthon of a lost and invisible world."
From Piece of Blue Sky
In the mid-1970s while in Washington, DC, Hubbard inaugurated a secret project to find out all he could about the "Soldiers of Light" and the "Soldiers of Darkness." The notion that people are born either good or evil and engage in a cosmic spiritual war can be found in Zoroastrianism, and in the Dead Sea Scrolls of the Essenes, whence it found its way into certain Gnostic Christian sects.

In short, there are a small number of "players," some Soldiers of Light, some Soldiers of Darkness. They are engaged in an eternal battle, using the "pieces" and "broken pieces" to achieve their ends.
