Newbie Guide:
There are plenty of folk here in the village who could use your help. Talk to them and they might offer you an assignment when you click on Quest. I will tell you of all the quests I know of for Mystics of your level, but there may be others that I have not heard of. Speak to the other villagers to discover their needs.
I can tell you that there are one-time quests that you may only complete once, but also repetitive quest that may be undertaken several times.
