- Despite it being a college you only have two lessons
- You were entrusted with all of the important quests despite being the newest member
- Tolfdir has no authority before the end yet he appoints you Archmage and himself first wizard.
So here is my suggestion:
For new members
Between every main quest have an increasing amount of lessons between before you can progress
- Each lesson you would learn a new spell, or perfect a current spell ( gain a level in that field of magic)
- You may have some individual/smaller lessons with a master of a certain field
- More students join after each main quest (maybe unnamed so it is easier to add more) so you arent the newest member by the end
Ranking system
For player
- Gain ranks after completing a certain amount of lessons in each field
- Ranks: novice/initiate/apprentice/ expert (maybe a more archaic name)/ master
- Gain am equivalent ranked set of robes in your chosen field
- For the other mages that joined with you
- You can help them with spells/lessons
- The more you help them the higher they will progress
Teaching Others
For people that have already completed the series then this would add more to do in the college
- Once you reach a certain rank (maybe expert) you can teach lessons
- Have to have a certain level (50?) in the chosen field to teach a lesson
- Another higher/equal ranked mage will inform you of the lesson plan
- You show the spell to the class
- 4 students, each doing something wrong
- Lesson ends when you correct all 4 students
- Gain a leveled mage-related item for each lesson taught
As Arch-Mage
Monthly Income
- Each month you can choose to spend the income on one or two things around the college
- Arcaneum- more staff or more lavish furnishings
- Hall of the elements- chairs and podeums, were lessons will then be held
- Bridge- Gradually gets more repaired as you pay more towards it
- Guards- More battle mages will appear around the college (like in the arcane university)
- When you reach the cap for all of those you can put money towards winterhold
- Can donate money towards repairing the town- more buildings will make an appearance
- About more citizens coming in:
- Can convince the jarl to persuade the dunmer who previously left to return- more dunmer (Some unnamed) appear around the town and the college
- Defences- when agreed some mage tower defences will appear around winterhold
- Can discuss the college with all of the jarls
- Can get donations (goes to colege fund not you)
- Can convince them to have a college ambassador in their hold, will spend most of the time talking to the court wizard
So this is my suggestion. I know some of it may be too unrealistic but I would be interested to know what others thought about it
