"The githyanki is the source of our protection against the Absolute. I MUST subdue him or everything we've worked towards is lost. Don't let my form deceive you. I am the one that's been protecting you. I am the one that came to you in your dreams. Help me." - This specific moment in the story connects the abstract, seemingly not-real moments that the player dreams of to a physical character that has effects on the story beyond what the player character sees/thinks alone.
