The server does need to earn money, and I personally don't see why they would be made obtainable with quests considering how many people have already purchased these and it would be extremely unfair to them. You can get them with store trades if you'd like - I've made all of my purchases with store trades, and haven't spent anything.
Also, you put Dark Lord in title - which definitely wouldn't be obtainable through quests. Its a roleplay prefix for the Seer currently with that role in roleplay. It isn't purchasable on store, so I'm not sure why you included it, it cannot be obtained as a student, and there is only one Dark Lord at a time.
