When I started my current campaign, I was new to Ars Magica and it was, in fact, my first time playing. Stuck in a somewhat D&D like mindset, I picked what I thought would be the best way to min/max my character without serious regard for RP'ing concerns. At the time, I assumed Dark Secret was one of those things that was reasonably easy to squirm out of, if it ever came up, which it likely wouldn't. My story guide tried to warn me, of course:
"You know, Tremere really don't like Diedne. Really don't."
"Eh, that's fine. My character can be all cool and conflicted because he doesn't like what his master taught him. He's still a good Tremere and all that."
"...are you really sure about this?"
And so on and so forth. Of course, over time, as I ended up appreciating that Ars=/=D&D to a far greater extent, and got in with the feel of it, I realized that this is a serious problem. It's inevitable that the storyguide will have someone find out, and when my character gets ratted out, he'll spend the rest of his (short) life running from the Broken Mirrors and Burning Acorns Vexillations. Even if he survives, of course, he'll be removed from the game by virtue of being on the run.
Knowing that my character is absolutely going to die at some point in the reasonably near future because the Storyguide has a duty not to reward my twink choice of charachter traits takes some of the fun out of playing him, however, rather then reroll or try to retcon, I've decided to roll with it and cut the GM off at the pass.
I'm going to confess.
Given that their going to find out (and they will find out), my only hope of survival, it seems, is to throw myself on the Tribunal's mercy on the basis that my character has always been loyal to the house. Has had no dealings with other Diedne, dosn't follow their twisted ways, loyal servant who sends regular Vis payments to Coeris, etc. Confessing certainly makes me look far more innocent then being caught red handed.
The problem is, of course, it's extremely likely they'll execute me anyway. I need a way to stack the deck in my favor. The obvious ideas occur -- make a lot of friends first, bribe key officals, etc, but given the Tremere's foaming at the mouth hatred for House Diedne, that seems insufficient.
Is there any way my character could reasonably hope to survive this? Any suggestions to improve his odds? This is, as I said, my first Ars campaign, so I have very little experience with Order politics. Anything you could offer would be helpful.
