Alrighty, I'll give you some background on the first tiny quest.
The main character's sister has locked herself in her grandmother's holding cell where she keeps a few valuable items. Missy unfortunately was overcome with curiosity and one night stole her grandmother's key from her apron pocket as she slept. Missy ran down stairs to open the gate up to have a look, and when she finally did walk into the cell, the gate slammed shut and locked her in from the outside. The sound of the metal clashing together caused Missy to lose hold of key and it fell through a deep hole within the stone floor.
Aaron comes down to the basement after a while has passed and finds Missy crying because she was stuck. She is afraid that if their Grandma finds out that she was down there without her permission, she was going to get into a whole bunch of trouble. So she asks Aaron, after explaining what happened, to go and try to find the key before her grandmother starts to worry were she is and comes looking for her.
Aaron asks her does she know where it is? She says that she doesn't know for certain, but the hole that the key slipped down may lead into part of the city's sewer system and it might be down there. So if the quest is accepted, Aaron would need to go down to the town's sewer system and search out for this key.
Hopefully I explained this little dilemma well
1. The sewer should be a maze, otherwise it would be just too easy.
2. It should be at least 100x45 (after all, sewers systems are quite large)
3. There should be an average amount of exits, but there is only one entrance, which I have already set up in town. The exits are there mainly to throw the player off within the maze.
4. There should be some doors, but all of them should be locked (as such town "maintenance" only has permission to be down there and they have the keys)
5. Rats...a whole bunch of rats and very small creatures that you would normally find in sewers.
6. BGM : 035-Dungeon01 (leave the volume pitch at 100)
7. BGS : 016-Drips01 (Volume 70, pitch 100)
And anything else you can think of to make it look really good.
