Rescue Your Sister
Backyard
Move to the building on the left.
Outside Magisterium
It's a very fancy looking door, but it's locked. The decorative silver orbs don't serve much of a purpose, but perhaps we can do something with the jewel-shaped hole above the door. Use the Jewel in the indentation to unlock the door. Move through the now-open door and into the magical mystery building.
Magisterium Foyer
A strange creature is floating around in the room. You can move through the door on the right without trouble, but you won't be able to Open the door straight ahead unless you get rid of the ghost. Use the Fruit on it to satiate its hunger, and it will leave you alone.
Optional
Open and Move through the door on the right.
Observatory
Nothing to do in here. You can take the Book on the table, but its text is indecipherable. Return to the Magisterium Foyer.
The door on the left is locked, so we need to Open and Move through the door straight ahead.
Laboratory
You can Use the Matches to light the wood under the cauldron, but I don't know that this does anything useful. You can also smash the beakers with the Axe, but, again, this is not especially useful.
At any rate, there's a safe in the wall. If you try to Open it, you'll be greeted by a combination lock. To crack this lock, you need to put two clues together. The Scroll 2 tells you that Gold, Silver, and Mercury together can form a key. And the Card give you the atomic number of those elements: Gold = 79, Silver = 47, and Mercury = 80. So just enter 794780 as the code, then press the A Button to confirm. Take the Jar 3 that was inside. In an act of extremely excessive action, Use the Axe on the Jar 3 to open it. Now you have a Cookie! Delicious snack in hand, Move back to the Game Room.
Game Room
Use the Cookie on the plate on the floor. The cute little demon will come dancing through, and swap out the Cookie for the Key 2. Make your way back to the Laboratory.
Laboratory
There's a metal hatch on the floor. Use the Key 2 on it to unlock it, then Move into the new entrance.
Cave
The entrance on the ceiling is where you fell from, and there's no getting back.
Optional
Move forward.
Spider Room
This is the spider under the Church. You can Use Stillini on it to freeze it, then Move past it and up into the Church. A handy shortcut if you didn't get the Star earlier. Return to the Cave to continue.
Move through the entrance on the left.
Frozen Cavern
There's just a giant wall of ice in here. The ghost of the Master appears before you, and tells you that Dracan is imprisoned in the ice here. Remember Diary 3's description of the Star: "In fire it freezes, in ice it burns." Just Use the Star on the ice wall. The ice melts, and the resulting flood sweeps you and an unconscious Dracan into another cavern.
Small Cave
Use Dracan on the hole in the floor. Once the evil wizard is dispatched, Move through the doorway on the other side of the hole.
Cavern Stairs
A stairway! And a door! Use the Key 2 on the door and Move through.
Study
The door slams behind you as soon as you enter, and you can hear your sister screaming. Better follow her voice and save the day! Make your way to the upstairs hallway.
Hallway 2F
You hear your sister's voice again! And it sounds like it's coming from above you. Move through the upper left door.
Scary Bedroom
Move through the door behind the bed.
Scary Bathroom
The door slams shut behind you, and it sounds like your sister is right above you! Just for fun, lets Use the bathtub faucet to turn it on. If you take another action, you see that the tub begins to overflow. The goal here is to Open the light on the ceiling and make your way out. While you can take any action you want, you can just keep trying to Open the light until the water gets high enough for you to reach it. Once you have it opened, Move through the new hatch.
Attic
It's your sister! She's unresponsive, so Hit her to slap her awake. No sooner does she wake up than a demon appears! It's done with her, and now it wants to possess you. Your sister jumps out the window, leaving you to deal with the demon. Use the Goblet on in, and the celestial water inside will vanquish the evil being. Once it's gone, Move through the window.
Only thing left to do now is to Enjoy the ending!
