Anyway, thought I'd share my meta here too in case anyone is interested since it's very Vala/Daniel focussed (though be warned that in the last part I'll delve a bit into Vala and Tomin's relationship).
The essay is divided in five chunks (for readability's sake and because it turned out to be freaking long LOL):
Part 1: Vala's backstory
Part 2: Vala's personality
Part 3: Vala and Daniel's relationship
Part 4: Vala and the team
Part 5: Adria, Tomin and the Ori
