Gramtoa is pretty clearly the remnants of the Liberty Step fantasy worlds after they were connected to Ordowald by Ranie. The layers themselves are really similar to Liberty Step areas, one really easy example is the Deserted City being Inviolable Vereela in Matar, or the Impure Lesion looking really similar to some areas in Malvis despite having a different color scheme. At the end of Gramtoa is one of the superboss fantasy gods from Liberty Step, the one for Renaliam named Aevelwan. He was one of the gods of the Godrealm that you also fight in Liberty Step. The characters you meet after the boss, Fram and Ratum, are basically the main characters of Liberty Step. It's a total follow-up to their stories to just see that they're alright now.
If you play Liberty Step, you'll see Renaliam is a special case of a region where the light Renaliam with all the people in it wasn’t part of the Godrealm, your character can't even be seen or interact with anyone there. Meanwhile there's a dark half of the world that was Fram's creation from her depression over being falsely accused of arson and having her life ruined over that. The bit at the end of Bottomless Gramtoa is very obviously the dark Renaliam aka Fram’s creation, and the light door you take after beating Aevelwan is the same as the ones from dark Renaliam in Liberty Step. Those doors teleported you to light Renaliam, and the one in awake is the same.
I don't think the Outside and Renaliam are the same thing though.
