Something doesn't add up regarding the connection between Amdapor and Norvrandt...

Ok, I see what you mean now,

To be honest, the Source people don't really use Astral/Umbral either in their dialogues. At this point, I'd have to replay the game and pay attention when they use the terms astral, light, umbral and darkness to see if they make any distinction. From what I understand, in Eorzea, astral and light are just as much synonyms as astral and darkness would be in Novrant.

yeap.. it's confusing..

They're totally separate concepts in Eorzea, and not used interchangeably.

The polarities (and eras) are referred to as astral and umbral, but never directly as light and dark - although you naturally might connect the concepts.

The Scions talk about the Light and Dark forces in the battle between Hydaelyn and the Ascians, but never describe those powers as astral or umbral.

It's here our reading diverge. Urianger is surprised to discover that light can be describe as umbral by his sejourn on the First. How would someone be surprised by something they already know? (That Astral/Umbral are entirely different concepts)
