🍁Nine Ancient Obelisks

After skipping, will there be another opportunity to visit the towns, or will the storyline for Asuguhom continue?

It won't be that easy for you to say goodbye to this land... For now, I'm still here, but the content of the locations may have changed over time.

Are Intelligence and Charisma now completely identical, or are they still used situationally somewhere?
Do I still need 300 on Nammu Ai?

Intelligence and Charisma may be used differently by other sources. For example, through skills. Yes, 300.
