My thought is that Vocis does it himself, with a one shot boost from papa's ghost. There is a broken supra-munchkin power on page 38 of RoP: Magic called "Grant Puissance in (Ability)". For every Might point invested, papa can give one man a +3 bonus to a specific Total or Ability. Papa can improve someone's CrVi total (or Magic Theory ability) just barely high enough to open the girl's Arts and retain supernatural virtues. That was papa ghosts one and only unresolved purpose in the afterlife, so once this is done his spirit is at rest and goes away.
Just an idea 
Oh my. I should have read the House Rules thread first. I have more exp and spells to buy from apprenticeship. (headsmack)
How does this level 15 power work? Looking at base guidelines, MuCo30 turns a human to an insubstantial object (Auram req), and PeCo40 can destroy (remove) the property of solidity.
What can base 15 do?
We're working on a different story. In its current form, Vocis stayed at her father's covenant during his third cycle while dealing with the Albigensian Crusade. The father, being a creepy Tremere necromancer, was having a hard time relating to his daughter. Vocis, being a doting father and grandfather, was able to befriend her and help out Necro Dad. They continued corresponding and Vocis visited regularly. In 1228, Vocis spends two fruitless seasons looking for an apprentice and returns to find the girl on his doorstep. Necro Dad opened her Arts with the intention of training her himself, but he died shortly thereafter in a horrific necromantic accident. Because the rest of his covenant sodales are also creepy necromancers, Ghost Dad guided her to Uncle Vocis to continue her training. There will be some kind of document (or something) 'willing' her to Vocis in the event of Necro Dad's death (or Ghostification), but I haven't gotten to the details yet.
Yep 
If you look at the Orphan Born in RoP:M, it's described there. Basically she can touch spirits when she is flesh or touch objects if she's incorporeal.
That works
Ah, I see. It lets you touch ghosts when physical and visa-versa. Incorporeal Form is a seperate power.
Finally! I'll post my third cycle back story and the final version of Vocis later today.
Right. She'll want to work on that as a MuCo(Au) effect post gauntlet.
You still need approval of a third player. I don't count.
But this is pretty well tamed and you should pass easilly.
I haven't seen anything that makes me go "Whoa, wait a minute, back that truck up, there, buddy!" yet, so I guess I'm okay with approving it.
There you go 
Hey all, I finally got around to posting my post-gauntlet Guernicus for your perusal. Please give me some feedback if you have any, and then I'll work on getting my cycles up.
Allrighty then 
Now that Vocis is complete, does anyone need a companion? I'm leaning toward a warrior-type, but I'm flexible.
Vulcanus would go well with a brother-in-arms or a failed apprentice, a forge companion, or a venditor. Or some combination thereof.
I would love to play a grog-level Tremere white wolf, if you (and Vocis) would be game.
I'll see what I can do.
I'd certainly be up for it, but considering I have a familiar, an apprentice, and three personal grogs, adding a white wolf would probably be too much. At that point I might as well get my own theme music.
Every PC should always have one's own theme music.
Vulc's is Metallica's "Escape"
OK, since things look good, I have one question: should I interpolate to figure out apprenticeship experience to now, or should I just do exposure experience and teaching experience based on her Vicis's seasons? The latter is far easier, but I'm very comfortable with math and can do the interpolation well.
