Prerequisite: Wizard class
You are fully versed in arcane knowledge, thanks to your rigorous training at a bona fide wizard's academy. You gain the following benefits:
- You gain proficiency in the Arcana skill and the Draconic language.
- You gain expertise with the Arcana skill, which means your proficiency bonus is doubled for any ability check you make with it. You cannot use the Expertise class feature to improve the Arcana skill.
- You have 1d4 plus your Charisma modifier (minimum of 1 total) former classmates who can serve as contacts or information resources, determined by your DM.

Has potential, needs work.
While draconic IS technically a very magical language, you'd get a lot more mileage out of this feat if you could pick any language, or from a set list of languages (eg. abyssal, celestial, draconic, infernal, primordial, deep speech, far speech) to reflect your scholar's magical theme/studies.
The Arcana expertise part is solid. You are a magic graduate so that makes sense.
The charisma score increase is too clunky. I recommend simply granting advantage on charisma checks to interact with former classmates (to persuade, deceive, impress them, etc.), or you could say they have a +1d4 bonus to such checks to interact with said classmates. Wizards and scholars usually have a bad charisma score anyway so this works better than forcibly increasing their scores temporarily (5e isn't so graceful if you are constantly changing your ability scores. The checks and abilities themselves exist to give bonuses there instead of the scores themselves. Ability scores work best when they are used as constants instead of variables if you know what I mean. 4e was clunky because it tried to fiddle with ability scores all the time, and we don't talk about 4e)
