Legend of Grimrock 2

The Guardians
Lore of Livingrock
The Forbidden halls, The Lost City and The Guardians.

I've finished all three mods and they all add to each other lore and story.

Forbidden halls is set under Al-Ator in distant past. The Lost City is future, when Al-Ator is destroyed. Possible reason: explosion in mines during The Forbidden halls. he Guardians is far future, when whole world is close to being destroyed. But they all set in same universe, there is tombstone in the Guardians with mention of Al-Ator.

Question: do it follow same storyline in: Forbidden halls, Lost city, The Guardians - and how long passed between each mod (centuries?).
Where are Lost City guardians? We meet only Watchers.
And Supreme Being it is crator of Goromorg, Ancient one is Goromorg and Being created it (from note in Citadel). Who destroyed Al-Ator, exposion or someone of them?
How distant in future is the Guardians?
