Sally, how about you sprinkle a few extra Warping points on your character and call it a Twiglit episode?
Roll it out using the online die roller
invisiblecastle.com/roller/
roll a simple die to determine how many points triggered the episode, and so forth. Post the results, and we will work together to determine a cool idea for a positive or negative effect.
Mind you, I HR'd that your V&F's need to balance when the character enters the game, so if a Virtue or Flaw is chosen then a corresponding opposite would be gained as a story result from your past (since gauntlet that is). To avoid this complication though, we can simply rule the Twilight effect is some sort of spell gained/lost or affects an existing ability.
Knowledge built on knowledge is power multiplied
So the Order is your power magnified
And its fighting on Magic's side...
Founder Bonisagus, he's our hero, he's going to take those hedgies down to 0.
Warping points:
invisiblecastle.com/roller/view/2669673/
4 points. Ouch. Well, could be worse.
Twilight avoidance:
invisiblecastle.com/roller/view/2669677/
1 Stam + 1 Conc + 1 Vim + 8 = 11
4 pts gained + (local aura) + 3 = 7 + (aura).
So whether Twiglit is avoided depends on where she was when it happened. I'm guessing it'd be at a covenant since she hasn't spent much time out in the world (maybe a lab event?) so probably aura 5, which means, bam. If it's not avoided then it can't be Twiglit, though, it has to be Twilight. 
Twilight Comprehension:
invisiblecastle.com/roller/view/2669684/
4 Int + 3 = 7
0 Warping Score + 9 = 9
No comprehension.
Not enough points for a new flaw, so I guess you should choose whether she loses knowledge or spells.
4 points from one event really does seem like a lot for someone with Flawless Magic and a good golden cord score, though.
LOL!
Sounds like a guy with a nice sound pragmatic approach to things. Just don't get on his bad side. And I for one -loved- that letter/essay that he 'wrote'.
I'm more of the type to consider the Order to fall under the idiom: "I stood on the shoulders of giants". As the unified hermetic code allows magi to do things that they could not learn on their own and push the boundaries of the theory where magi could reach higher powers by reading books and such than what they would learn through experimentation. Although that might explain why I prefer house Tremere over most houses in ars magica (and they are my 2nd favourite clan in Vampire back when I played the game over 10 years ago).
Perhaps it happened before you enchanted your familiar and is what inspired you to take such a high golden cord. You may have only had a mastery of 1 in that spell, perhaps you were taking down a demon in an infernal aura using a lot of vis. I once rolled nearly 30 botch dice on a bad spell with my Jerbiton magus. I had dropped a butt-load of vis for penetration on a frost giant in Ultima Thule. My familiar had been killed a few years earlier by said frost giant ( 
), but I had the spell mastered. The end result was only 4 points of warping and I lost mastery xp from the spell.
So, choose your result. You loose a 4th magnitude spell (prolly the one you botched), or you loose Mastery xp in that spell (or xp from somewhere else), and you get to pick a cool twilight scar.
I recently red Van-Huse in the WG fro ArM3. Interesting stuff. I think the same or a similar letter was in the WGRE for ArM4, but it has been a long time since I read that section of that book. I think I will go over it again for nostalgia. Some of the other ArM3-WG letters were shocking though. There seems to have been a hostile relationship between magic and the divine back then. And the letter on the Reason Aura is simply ridiculous. I know there was a Reason Aura in ArM3, but the whole concept just seems so ridiculous to me.
You mean Flambeau, the true hero of the Order :mrgreen:
No, he's the punk ass replacement for Wheeler. DUH!
Resisting..urge..to smite you...with...bolts of fire....
Flambeau is all well and good, but I'm a bigger fan of his Filius.
I'll just ask Bjornaer to use the power of Heart.
I wondered if anyone else would get the "Captain Planet" reference. Apparently so...
I prefer the take on Ma-ti's "power of heart" that showed him with a bloody, Aztec-style offering. I mean, honestly, "Heart"? It should have been Aether or else the Quintessence. Or at least something like Spirit or Life.
Oh please...
Not that 'you' are biased or anything? 
Amen, again!
Apromor!
My take is that there are all types in the Order, that it is a vibrant constantly juxtaposed hodge-podge of all of them. And that is what makes it interesting. It isn't all cooperative. It isn't cut-throat antagonism. It is both, at the same time.
And Tremere were probably my #1 Clan. Ventrue the close second. Everything else... meh.
What, no Malkavians? Malkav has long struck me as Marauder-by-Embrace.
More seriously, do NOT mess with Clan Giovanni. They can swap your souls out for those who went to Final Death. Lose an enemy, reward an ally, gain a new soul-slave.
Though I'm still trying to figure out what a "family" of Venetians is doing with so many Sicilians high up on their payroll.
Ventrue was my favourite, then Tremere, then FOllowers of Set. After that I didn't really have a preference except my utter dislike of all the Sabbat clans except for city gangrel.
