The original The Tower release, augmented with two tracks that never made it to the original album.
Those two tracks were consequently remastered and remixed, with additional vocals.
High King is centered around Fingolfin.
The Library is a strange offshoot of eldritch proportions.

Cover art is a collage of the original The Tower artwork with Yōrō Waterfall in Mino Province by Katsushika Hokusai and various other stuff taken from the MET online CC0 collection (no artist credits are given as it is mostly textile scraps without attribution).
All my thanks to the community.
