Harper encounter help

Hello all,

I've had the Harper encounter, which turns out to be a Wight.
Does anyone know what the challenge rank for a Wight is, and do you get
if victorious?

XXXXXX neared the end of a week's travels and came to a large hill
encircled by smaller ones. Near the top
of the center hill, he saw a dark opening from which spilled a slow,
hauntingly beautiful music. Briefly,
the melody held him entranced. "Surely the Song of Creation," he
thought, "could have been no sweeter."
Working his way between the lower hills and up the large hill, he came
to what was, upon closer examination,
obviously a shallow cave. Barely visible in the cave's shadowy recess, a
dark figure bent over a softly
glimmering harp. Still pulling at the harp strings, the figure looked up
and its eyes flickered with the
same light that came from the harp. A sibilant whisper insinuated itself
in the music, "Who disturbs my
solitude?"
