In another thread, much mention was made of "gifted lab assistants" who were not apprentices, and, hopefully, not able to ever be apprenticed, for whatever reasons. The perfect lab assistant.
Age might be one deterrent to being apprenticed, but is not an absolute barrier - if the Parens is willing to try teaching an old dog new tricks, good luck. Pre-existing Supernatural Abilities might also exclude a magus whose InVi lab total is insufficient, but, again, it's not an absolute - in theory, there is some magus with a focus in InVi who can open the arts of even the most supernatural of apprentices.
But the virtue "Failed Apprentice" (p 42) specifically hints at other elements that completely prevent completion of apprenticeship, an "incomplete Gift", or "some griveous mishap". But most importantly for successful magi, the failed apprentice ".... may learn Magic Theory and serve a magus as a laboratory assistant." And the ears of magi perk up across the Order...
So...
Has anyone ever delved into this corner of the rules, and sprung some "grevious mishap" on a magus' apprentice? If so (or even if not), what sort of mishap would you suggest? How/When does a Parens realize their apprentice's Gift is "incomplete"? How rare/common would be this unfortunate turn of events?
Would it be possible for one Parens to be unable to complete training, but another have the Arts or insight to complete the task? Once "failed", is there any hope to complete the regimen of apprenticeship, to prove themselves worthy despite their initial failings?
If the Failed Apprentice is sufficiently magical to attain the status of "Hedge Mage", what process would then welcome them into the fold of the Order? Or is their fate sealed, to either be marginalized and patronized for their days, or perhaps quietly marched as an embarrassing footnote to one Parens' failings?
(In theory, an apprentice who consistently fails (and yet survives) their Gauntlet would fall into this category, tho' they would certainly be too magical for the Order to ignore. Perhaps they would simply be stamped "Ex Misc" and then carry that stigma for their days?)
What parts of the Code would apply once an apprentice is labeled "failed", and the blood hits the water and magi realize this potential lab assistant is no longer protected as an apprentice?
Assuming a reasonable grasp of the realities of the Order (and their situation), what could a recently Failed Apprentice do to prevent mere, immediate and indefinite slavery? The passage in the virtues mentions "welcome" and "compassion", but imo that sounds like wishful thinking, and euphemisms in the same way that many slave owners were compassionate as they welcomed their new property.
