^ Gabranth is definitely a contributing factor here to the writers, I think. I agree. Trying to show opposite ends for both of the legati who are relevant in this expansion.
Unrelated to that but still Werlyt talk:
I really think they should have used Zenos for Emerald's Oversoul and saved Gaius for Diamond. He's more relevant and thematically important to this plot than Zenos is, it would be better to have the last Weapon use Gaius as its Oversoul.
