Rune mages availability

[Youpiya]

Hello,

I've not played KB since a week and want to take my last game save. The problem is, no rune mage seems to be sold after Guilford fight and fight after fight and leadership increase after leadership increase, I still have only 52 rune mages.
I read that I could use the old shoes in arlania in a quest, the thing is, I transformed it into crystal at the begninning of the story.
So my question is : will I have the ability to buy rune mage elsewhere in my adventure ?

Tx a lot for your help
