The fragments from the Proto-Planet, or Gaia fragments as I've called them in the placeholders, will be somewhat thematically linked to the colour of the associated Archdemon. Ludus has the lush and green Wonder Jungle, which fits in with Leviathan being associated with the colour green. From here we can speculate that Pragma would have a desert-like area, Mania would have a grassland of sorts, Agape would have a large glacier not unlike the north pole, and Storge would have a large lake. I personally can't come up with anything for Eros and Narcissus. Something all Gaia fragments should have in common is that they function as randomized "dungeons" upon entry, making use of scrambled zones and pockets of warped space to fit far more stuff in there than what would be logical.
