I would argue that both the title track & Dodo/Lurker from Abacab continue the 'fantasy' theme if that's what you wish to call it.
Yes, but by "fantasy" I don't mean the subject of a song (or the vague theme for an album). To me (and from what I've understood, to Eclipse also), it's more about the music itself, the atmosphere it carries (from ethereal, like the acoustic part of Cinema Show, Blood On The Rooftops, Snowbound, or Heathaze... to bombastic epic things like Watcher, Apocalypse, Eleventh Earl of Mar, Duke's Travels...). All those things that generated images or dreams in my head when I was younger... When you're young you associate things in your head (sounds, pictures...), even if it doesn't make any sense. You're making up stories (I was...).
I discovered Abacab later, so it's maybe because my brain had matured at that time that the music didn't have the same power of bringing images into my head...
It's probably why, to this day, I'm so attached to this 1970-1980 period.
