I have been reluctant to share details of my latest saga, intimidated by the many longtime players here. However, as I read the current thread on apprenticeship and XP-boosting virtues, I thought some might find our experience useful.
The new saga is officially called "HBO Ars Magica," with the conceit that it is AM as a cable channel might produce it, inspired by shows like GoT, Sopranos, or the Wire. However, our "first season" covers apprenticeship and is set in the Greater Alps. I picked the Alps because it was a good way to kick the pcs out of their current situation at the end of the season, as the newly-Gauntleted magi are exported to the sea. With the Hibernia book expected soon, we are planning to spend Season Two there.
The game has only met a couple of times. We pass a year between sessions, to move through apprenticeship in a timely manner. The saga began in 1205, so the PCs would be taking their Gauntlets in 1220. Because this is the Greater Alps, their masters and covenants have access to a lot of resources, and I think it is fair to call this a relatively high-magic game.

In brief, twenty Gifted children were brought to the Alps by a redcap, who was in turn intercepted by rogue magi and murdered. The children were led off and briefly squabbled over by the magi before the children were found and rescued by the Order. The children were presented for selection by Alpine masters and, over the course of the year, their Arts were opened and they began instruction in Latin and the liberal arts, in a school-like setting.

While studying together at the covenant of the Icy North, four of the children were led away by a ghost to a remote chapter house, where they were forced to fight a giant. Eventually they found their way back.
Elsewhere on the site you will find stats for all the PCs and NPCs, including various magi from Snctuary of Ice which I have updated for 5th edition. My thanks to Timothy Ferguson, who graciously answered some questions from me in this regard.
