Thieves Guild, Mutown, and The Cloud Canyon
This is IGN's Guide of the Thieves Guild, Mutown, and The Cloud Canyon. In here, we will give you directions on where to go in case you're lost and also point out where a fairy might be hiding! You'll also be tricked into joining the Thieves Guild in this section if you want to retrieve the stars that they've stolen from you!
After clearing the Clank and having your stars stolen from you, step out of the cave and another zone for you to explore will present itself. Approach the save crystal to save and immediately head to the southwest of the crystal. There'll be a maze in which you can solve using your rat form so be sure to change to that form before tackling it.
There will be chests around for you to pick up and monsters chasing you around the maze. After getting the 2 chests, head upwards towards the merchant. Beside the merchant will be one of the demi-dungeons introduced by Armanda, the Ancient Robot.
But since you still don't have enough stars, continue to the west until you pass a save crystal and go to the south. To the Thieves Guild we go!
Thieves Guild
The Thieves Guild is located in a small zone called Tarview Lake. Just like what the thieves guildsman told you, approach the house with a blue roof. Once there, interact with the door and choose "Password". The door will open and you'll meet with the other guildsmen.
Once inside, the guild leader will be waiting for you with your stars lying on the table. He tells you that the only way for you to retrieve your stars would be to steal them. You do that, but it was only just a ruse to get you to join the Thieves Guild.
The Thieves Guild, just like the Round Tables Tavern, will be a hub for sidequests.
Mutown
Mutown is just right beside the Thieves Guild. You're free to explore Mutown, but we highly recommend going to the northeast of the town first towards The Gulp. The first thing you'll notice is that there'll be another maze for you to navigate. It's pretty straightforward, if you're lost, refer to your mini-map at the upper-right corner of your screen.
Continue heading north and you'll discover a cave in the middle of a lake. Continue north of that and there will be a chest lying in wait. Once done, go back to the lake's entrance and head west this time. Open the fences. There would be two. Also, pick up the fairy for the additional mana.
Once you're done, head back to where the Thieves Guild is. Just southwest of that, there'll be a house with a fairy inside it. While there'll be a Demi-Dungeon called "Moletopia" just to the east of that house.
Cloud Canyon
After you're content exploring Mutown, it's time to move to the Cloud Canyon. Head back to where the Merchant is on Mutown, but this time instead of going up to The Gulp, we're going down. First thing you'll notice as you take your first steps in Cloud Canyon is that there'll be a fox speaking to you and that the whole place has poison clouds everywhere.
You can use the Ghost and turn Ethereal to avoid accumulating poison, but we found that just rushing through it also works. This zone is pretty one-way. Not really offering much in exploration. Just make sure you're following the pathway and you'll reach a cave.
Make your way out of the cave and there will be an encounter where you'll be pitted against torso enemies while there will be fences around. So the only way out of this is to fight. There'll be a couple of encounters like this with different enemies. Just fight your way out of them as quickly as possible so you don't accumulate poison.
At the end of the road, there'll be a demi-dungeon called Morning Star Powerplant, a merchant, and a teleporter near them.
Rustrock Barren Hidden Fairy Location
In Rustrock Barren, there is a hidden entrance that contains a fairy. Just to the northwest of the Ancient Robot, head to this spot.
The rocks there indicate that this is an entrance to a cave. Go inside it, there's going to be an obstacle course waiting for you! It is recommended to use dodge and ethereal to solve it. Once solved, there's a fairy waiting at the end!
