What magic college could I have gone to before Hoard of the Dragon Queen?


I’m joining a running campaign of HotDQ where they just finished a chapter (I don’t know which, but the DM says everyone’s level 4) and I’m looking for a lore-friendly magic college to be part of. I’m playing as a level 4 Tiefling Sorcerer who meets up with the party while investing and dealing with reports of "strange happenings"in the area.

What magic colleges (or universities whatever) are in the forgotten realms that my character can be a part of?
