Yeah that 'first darkness' is probably just Gandrel reciting his folklore, nothing much in it. The MM says hags originate from Feywild. 5E lore is solid for backwards compatibility so likely matches FR hag origins.

Back to OP's post. The game really ought to switch to turn-based when a character is dying. Let the player stay in or switch out thereafter, that's fair choice.
