Many of the survivors of the great magical cataclysm were apprentices of various ages and skill. These abandoned pseudo-magi, have been left to fend for themselves. Either through completing their training on their own, or seeking out fully trained magi to do the same.
If characters wish to train apprentice’s later in the saga, they may do so as normally described in the core rule book. No other penalties or difficulties are applied. It should be noted that all magi consider their apprentices to be their property until released. As such, magi are extremely protective of them and covet the apprentices of others. Magi would be wise to remember that the normal legal protections of apprentices are now, extremely difficult to enforce. As such, protecting their apprentices becomes much more of an issue.
