I won't be surprised if it is a crisis for him but I doubt he'll turn to red lyrium. That's where Josephine might come in with her connections, maybe a trade agreement with the dwarves?
Two things have hit me that I had assumed were correct but I'm not sure now. One, I always thought it was a given that the Chantry used lyrium as a form of controlling the templars and two, that advisers can't die (for some reason *I think* I heard that companions yes, advisers no but now I have doubts I heard correctly)
I dunno, if all the templars are truly addicts, then if the withdrawal symptoms are strong or unbearable enough, then maybe that's why we have Red Templars? At least, some of them anyway, not all of them. But I didn't think about Josephine and her connections, oh good. *relief* This means my Quizzy won't have to tie Cullen to a bedpost or something while she goes off to find a solution/more lyrium/a cure.
I did say my thought about his crisis point was farfetched. although I don't really think my Quizzy would need an excuse to tie Cullen to a bedpost *whistles*
I think it is a given that the Chantry used lyrium to control the Order. We know that Alistair definitely says as much, and I know Evangeline says something like, "Once you're in the Order you can never leave," when Rhys comments on her being addicted to lyrium in Asunder.
I think the advisors might be able to die? Although I'm just going off of the E3 demo and the cruel cruel clifhanger they ended it on with Leliana and the knife to her throat and the look in her eyes. But if they can die, then I think as players, we'd have to try really hard to get to that point? Since the advisors are super important and all. It would definitely make the game a lot harder if we could lose our advisors in some way. Say you lose Cullen, so your troop numbers start diminishing because he isn't there to lead the armies in your stead, or if you lose Josephine, you start losing resources and alliances because you can't meet the requirements for trade and political deals she had made, and if you lose Leliana, it becomes extremely hard to keep an eye out on what's happening in the different regions, even the ones you have control of, because you've gimped your intelligence branch.
But again, I'm only going off of the E3 demo. I don't think that they advisors can die, because again, they're super important and they seem necessary to the gameplay as far as running the Inquisition goes.
