Hi all,
I know the glass cannon network often uses Syrinscape for many of their actual play shows. There is a background string instrument / soundset playing in their show Legacy of the Ancients (season 3, episode 8, 43:00) and it sounds like some of the Witchwood but not exactly. It sort of sounds like Aeon but not exactly. So I suspect it might be one of the soundsets. If you recognize it as part of (or not part of!) a syrinscape soundset I would be very appreciative to know.
