I am at Level 15 and have completed the quest 'Wolf Wool for the Charms Enchanter Wizard' yet I seem to have hit a wall.  The same quest is available to select again however now I am told "You have came too early", which I don't understand.  One thing I have noticed is that the completed quest in my Quest Log states - compared to other quests I've done - 'This quest was passed (times):', telling me that maybe this quest can be repeated over and over again, possibly to farm for Sapphires.  Do you have to be at a higher Level each time you want to repeat the quest?

Beyond the Magician's Tower I don't see any other quests around to further progression.  The Lair of Snakes have been completed.  I only see 2 other available pathways, in Arcfort Forest, but both are blocked.  I am guessing entrance through either of these is restricted to future development of the game.
