Lots of dark gothic moods conveyed here. There are both subtle and dramatic use of tone colours and dynamics.
The music often conveys a sense that something is about to happen. The overall mood of the album is ethereal and sombre, and therefore is an ideal soundtrack for a movie or animation, which has an ethereal and sombre mood. There are contrasts also, for example 'Danger', which does indeed convey a sense of danger, and L'Assault, which must be for a battle scene. Well worth a listen.
