This issue has came up in the past, the last time I remember was when Culinane
was charming the black sun during an attempt to raise the long night, so that
he could lead it back to his patron's temple and kill it in safety.
He'd also bring Wykoshia from Azrili all the way to the sun and try
to kill the cultists that way. At the time I was told it was a bug and that it
was being coded to stop the exceptional ccc's such as those two from being charmed
as it served no purpose. I certainly haven't seen either charmed since but
that may just be coincidence, however, it may just be that Bezejeth has been
overlooked.
