Im surprise no one talk about the diviri parts , my friends and i where talking about it and it somehow close to a other latin word that interestingly had the following meaning's
to have or keep from someone to owe something, to be under obligation to and for something to be bound, in duty bound to do something; "I ought", "I must", "I should"
Its funny but it does fit the theme of maybe us causing something to set the timeline in motion, as we owe our power tot he void demon what i love even more is the under obligation what if we are the one who causes the void demon to affect the adult and well cause everything that had to happen to happen effectively creating a Paradox.
As for the Dax because if you look at is katana its very very much the same as dax one even is way of holding it is almost the same as when dax was holding it toward us, but the whole skeletal and how he is made really make em Think of Nidus deluxe for some reason its just a bit similar, Which funny enough nidus mean's:
a place where something originates, develops, or is located
which yet again fit the thematic but yeah im just throwing ideas
