MacLeod's description:

Genre: Soundtrack
Length: 3:26
Instruments: Strings, Flute, Clarinet, Oboe, Celesta, Tympani
Tempo: 89

This is sort of "Spooky Light". It is dark yet playful in a sense. Good for fairy tales or light tension building. It has several small arcs in it - but loops back to the begging.
