Uhhh...
I haven't thought as far yet.
Who knows, maybe we'll get to see Shiori as a little girl.
The only returning Myst Zone maps are Entry to Demise and Blood Garden (as the Shining Garden).
Who knows, maybe one day, we'll get a Myst Zone-only work, starring our mysterious Shiori Shauntal as the protagonist.
So, we have:
(Front) Shining Garden; House; Inferno Passage; Emeraldsand Beach; Tainted Shipwreck; Entry to Demise
(Back) Valkyrie Graveyard; Corrupted Garden; Spiral Hell; Slumber of Life; Exit of Fate; Nonexistence
Six maps for the front, six maps for the back.
Is there a middle?...
......
.........
You know...
I never thought about that.
Will I ever find a harmonious cat to play the banjo?
...
But seriously, it just occurred to me that the Myst Zone could have a "middle"... but I've already decided upon the layout, so...
I'VE GOT IDEAS AND I DO'NT KNOW WHAT TO DO WITH THEM AAAAAAAAAH--
