I mean, they could use clever writing to establish there’s mobs from the Alliance that did want to go full deus vult – Handfuls of those who were never satisfied (which would be more realistic too). Maybe make a splinter faction due to such discord or have a political scheme start within the Alliance’s own ranks and create some inner-strife & conflict.
The Alliance could use some inner-conflict
The argument that: “Oh the Alliance doesn’t do inner conflict. We’re the epitome of unification to overcome conflicts & nothing else!” — or something along those lines, just becomes a boring concept. lol
As someone else once said in another thread:
That is just dooming the Alliance to be stale forever. There is no personality. There are no lines to be crossed or not to be crossed when it comes with different cultures. There is only the Alliance.
