Arc the Lad

Arc the Lad:  In a later episode the main Villain casts a spell that sends 
darkness everywhere.  The heroes block the spell but the villains female
sidekick starts sinking into the darkness.  She pleads and reaches for the 
villain but he pushes here back and lets her sink.

Review:  This scene was pretty good.  Not really quicksand but it
did have quicksand sounds in the background.
