I thought you where suggesting that the "two different things in-game" where actually the same thing.
There was a powerful weapon the nautaloid - Shadowheart was on the nautaloid - Nightsong is a powerful weapon - Nightsong is a female person - Shadowheart is a female person
Oh no.
I was talking about the weapon everyone is looking for. It's clearly the artifact for the Githyanki, but it's a bit unclear what is it for the Absolute as their servants seems clueless outside "it was on the ship".
And while the artifact is called a weapon, so was Shadowheart (called a weapon).
So which weapon does the Absolute wants: the artifact or Shadowheart.
What if its both and the gith artifact holds her real memory/powers
