I think we should start with general playing quests and eventually add quest trainers in each guild. The general playing quests would be stuff like going to slim's, finding okef in the tinker guild, buying and selling items, finding the magical cavern of knowledge and using the transport runes in the cities. The reward can be anything from just XP and money to items. (ie - Newbie quest trainer sends you to okef to repair his weapon. After you complete the quest, the trainer rewards with xp, money and an unsurpassed iron weapon of your choosing.)

I think the general playing quests should level you from 1 to 3. Then the guild trainers will level you from 3-6 with specific to guild quests.
