Not all Jerbiton are Gently Gifted. A supremely talented artist could be Blatantly Gifted and would still be welcomed into the house. I could see that working for the deceased elder, the heir, or both.
There could also be a quite warlike Jerbiton who fled from the aftermath of the battles in Constantinople, depending on the timing of the saga.
@arthur would you mind making us individual threads for character stuff? You can actually create a thread as us (the bot taught me that last night) so the top post for each of us can eventually be our character sheet, after the discussion below that resolves itself.
I'd also like to ask some mechanical questions about magic, if we could have a thread for that I'd appreciate it. 
Since each of us will probably have several characters (magus, companion, grogs, possibly familiar or apprentice), I propose having a single topic (by player) for the creation of all your characters. The same topic can also be used for discussions as the evolution of the characters. This would keep the final character sheets separate, as it makes it easier to find details about the character that way.
Eventually, we can also have an index wiki post to refer to all active characters.
I'm reading this two different ways, sorry. A single topic by player for all characters, meaning one player has one topic with all characters? But then you talk about discussing characters in the same topic, making me think maybe you mean all characters have their own topics. Sorry. Thanks.
One thread per player but with multiple characters makes sense, keeps things from getting too cluttered.
I assume our threads will have the info for the grogs and companions that we play, and not the ones who are associated with our magus?
Yes, this.
For example: "Character Creation for Plot_Device (OOC)"
Yes. Though grogs are more held in common, so just because I create a specific grog doesn't mean you cannot play him for a specific story.
There should be troupe discussions about companions at some point also, since we will want to create companions that won't, as far as possible, interact with our magus. So we may look at companion concepts that are good fit with the magi of other players, and a bad fit with our own.
Do we want to figure out ideas for companions first, or do we want to get the magi all finished and then figure out good companion ideas for each one?
It's not a "either or" situation. Nor should a companion concept be "paired" to a single magus.
It could be a discussion similar to the magi's roles. What mundane roles do we want to play? What would fit well with the covenant?
I'd be in favor of waiting a bit, but if someone already has a strong proposal I don't have a problem with developping that companion right away.
Did we decide on an agreed range for post gauntlet? (Using Arthur's nifty narrative system)
Most of you seemed to be aiming for less than 10 years post-Gauntlet.
Are we still going with the themes/roles for the various magi? I thought you were going for the Mundane Ambassador/Voice.
Not impossible for a legendary strong Merinita, but that might make it difficult to also take Gentle Gift.
Yeah, that's part of why it takes me so long to build it up.
But l want to play Gentle Gifted magus.
I was actually thinking of a version of teleportation that I want to hear the groups' thoughts on.
Teleportation through water. Ie linking two lakes or waterways, walking into one, then appearing out of the other. An arcane connection would be needed of course, and I reckon it would be ReCo(Aq), but probably thematically more akin to the focus of Aquam.
For her years post-gauntlet that is
My initial thought is that this sounds more like Hermes Portal (ReTe 75), rather than the regular ReCo teleportation spells. Unfortunately, that also sounds like something that would require Original Research (or at least a very favourable result from Experimentation).
A thematical ReCo(Aq) spell sounds nice too (for flavour and aesthetics), but the Focus wouldn't provide any benefits.
It would be a really cool bit of original research to do I think, so it could make sense for a long-term goal.
Hmmm... isn't there a "Waterway" range somewhere? Maybe it's could be a variant of road (faerie range?)
Teleporting anywhere along a river... with the river itself before you, there would be no need for an arcane connection.
Atlantean Magic (RoP:M p.43) has a Range Water-way and a Target Body-of-water in addition to its Duration Storm.
Hmm interesting, I will read up on Atlantean Magic, that might the souce of her powers after all...
Just because something existed in the past doesn't mean your character needs to be linked to it. It may just serve as an inspiration for her research.
Your maga's design is elegant right now. Trying to mash in another thing might not be beneficial. Just saying...
