Canon is Mercedes Lackey's 'The Last Herald Mage'.

Are you really sure this is a good idea? It's...been a bit and the last time you tried this it didn't really go anywhere. Besides, I have more important things to do, especially as now I'm recovered and apparently getting my Whites. I fail to see what you consider so important as to over ride that. Just leave me be, and concentrate on your others. I want no part in these 'games' when I still have all my training to get through at the Collegium.
