The Mystery of the Stoneybrook Key
How to Solve
1. Go to Stoneybrook. Once you enter it go north one map then one map west. You should see an NPC next to a dirt hole.
2. Enter the dirt hole. You will have to clear 7 (?) maps. You cannot go to the next map until you have killed all the monsters.
3. In the last (8th?) map find a key and return using the portals where you came from. The maps might have reset but you don't have to kill all the monsters to return.
4. Give the key to the Sage and he gives you an expensive camera and film.
