Angels of Isolation

Of all the strange angels, the angels of isolation are perhaps the oddest.  They are charged to never communicate or be in the same company with either people or angels.  They are to make their own way in the worlds created.  As the eons roll by, the isolation tends to make them even stranger than most.  What they do, though, no one can say.  And if they could say, they would not.  A mystery remains.
