And secrets? What about the Seekers? Templars? The bloody Chantry? The Council is a bloody bomb waiting to go.
And for such an old organization they are surprisingly simple minded and free of visible corruption.
It's funny that you mentioned those groups because they suffered ridiculous levels of corruption and other problems.
Cass literally says "You begin to think that you are the only one who can solve problems" when talking about the Seekers power over the Circles. The Templars and the Chantry were both extremely flawed organizations before DAI. Much of DAI is about reforming the Circle and Chantry system because it didn't work.
You're gonna have to explain how the Wardens are free of visible corruption.
- They claim to be forbidden from interfering with politics, but they do. A lot. Djikstra from Witcher says it best "That's just an excuse you pull when the temperature gets to hot" (paraphrasing)
- There is no group outside of the Wardens that knows how to kill archdemons and the Wardens are content to keep it that way
- The only reason the First Warden cared about the Ferelden wardens is because they got legal ownership of an arling
- Dryden rebelled against the king of Ferelden
- Clarel was making a demon army with Erimond
etc.
The Wardens are basically DA's version of Cerberus. The HoF being part of the Order doesn't make a single difference.
