Litz is a small town that also has a port to the south (also named Litz). The first building you come across is the town Hospital. Dr Emilio is the head of the Hospital, and all of his patients like him because he treats poor people like them. Litz's only product is Sardines (those tiny little fish) but they have no way of processing the fish so they can trade with other towns. The townspeople also talk of the castle to the east called Sylvain. There once was a queen who ruled in Sylvain, but then her 3 sons died while on an exploratory voyage. She the went insane with grief and people are afraid to enter the castle because no one has ever returned back outside.
If you visit the Inn Royd will be there. He says that Princess Elle has gone missing, right after King Henry died. He finds it very unusual. Also in the upper left corner of Litz there is a treasure chest. Before you go to Sylvain Castle, stock up on ElecRings from the Magic Shop in Loire. Buy as many as you can. You'll need them later if you want to finish the castle quickly, else don't worry about it.
Leave Litz and head toward Sylvain Castle. When you get there, the place is old and run down. There's even acid in the fountain! Go through the courtyard and head into the castle.
You can also go through the doorway in the lower left corner, but it just leads to a dead end with a StarDew at the end. The correct path is up the stairs and up the left staircase.
When you arrive on the second level, you'll find three more pathways to go. There is a doorway to the south and north, and a staircase going down to the east.
The next room has three more exits to it; one in the upper left corner, a staircase in the middle, and an exit in the upper right corner. Take the doorway in the upper left first. It will lead you to the Guard's Area and Storage. In the back of the Storage room there are some treasures. You will need the Tower Key from one of the chests to unlock some door's you'll come across.
This time take the upper right doorway, which leads you to the Dining area and the Kitchen. In the Kitchen there will be a stove fireplace on the north wall. Crawl through the fireplace and keep crawling until you discover the Black Opal hiding among the soot in the fireplace. Crawl back into the Kitchen and exit out the door to the south that leads back outside.
Now that you are back outside the castle, you'll see a tower to the east and a tower to the west, but the doors on both of the towers are locked. Go to the eastern tower, equip the Tower Key and then use it to unlock the door and enter the tower.
Defeat the guard and the gate will open. You'll end up in the sewers, where the water has been replaced by the same purple acid you saw in the fountain in the courtyard. Walk through the sewer (there's no way to get lost; just follow the path) and you'll eventually come across a series of statues that look like snakes. The middle snake appears to have something in it's mouth. Reach in and try to grab it. A switch will activate and all the acid will turn back into water. Walk back through the sewers, exit the west tower, and head to the west tower.
Unlock the door on the western tower and climb up the staircases. Ark will eventually reach the top of the tower. Yomi will notice on the wall of the eastern tower there is a stone relief that looks like a snake, but something appears to be embedded in it's eye. There doesn't appear to be any way to reach the east tower from the west tower, until Yomi pushes you off the side of the tower and you have to hop from rooftop to rooftop to reach the east tower. Once you reach the roof of the east tower, climb down the vine and grab the jewel out of the snake's eye.
Return back to the main floor of the castle, go up the staircase, walk past the paintings again, and go back up the staircase on the western side. You'll return back to the three-way split, so head south back into the chandelier room.
Return back outside the castle to the courtyard you first walked through. The fountain that was once filled with acid is now filled with water again, so jump into the fountain for a swim. You'll find the Saphire gem in the water. Go back inside the castle and walk up to the paintings. The jewels will react strangely, and start placing themselves into an eye of each of the paintings. Once they are all in place, a chandelier falls from the ceiling and creates a large hole in the floor in front of the paintings. Jump into the hole.
Once the real monster is destroyed, head toward the eastern room in the dungeon. You'll see some poor guy huddled in the corner. Talk to him, but the only voice that you'll hear is someone welcoming you to her room.
The next challenge is a game of "Simon Says". The monster is at the end of a long corridor, and as long as the monster is saying "Simon says walk" you can walk. But as soon as she says "stop", you must stop and not move until she starts chanting again. If you do walk while she's not speaking, she'll send you back to the end of the corridor and you'll have to start walking toward her all over again. The closer you get to her, the faster she'll speak. When you get close to her, hit her with your spear and she'll start crying for her mommy because "Ark is being mean". Suddenly you're transported into another room.
Bloody Mary is one of the most difficult boss monsters. She has around 300HP, but the spear you have equipped will only damage her around 2HP at a time. It's best to equip the Light Rod (or the Silver Pike) as the weapon because they gives the most amount of damage even though it maxes out at 4HP for the best hits. This is also where the ElecRings come in handy. Equip the Jewel Box as your item and use those ElecRings. The ElecRings can do around 46HP of damage to Bloody Mary, so it's easier to fry her with ElecRings then take the time to hit her with the spear.
If you are stuck having to hit her with your spear instead of using ElecRings (or if you run out of ElecRings), keep moving around the room in a circular motion. Bloody Mary has those 4 jewels that circle around her feet, and she will even take off her face and throw it at your last location. Even the circle of jewels will chase you down, so it's important to always be moving. Bloody Mary will mostly be in a position in the room that will overlap your circular pattern. If she was at the top of the screen, you could start from the upper left corner, run to the lower left corner, run to the lower right corner, run to the upper right corner, begin to run back to the upper left but since Bloody Mary is in the way, you can do a dash/attack combo or even a dash/jump/attack combo. If you're lucky most of the time when you run through her to hit her, you'll completely miss being hit by one of her jewels. Even getting hit by one of her jewels or her face that she throws around can damage you in the 30HP range. The battle may take up to 45 minutes if you're stuck running around the room and hitting her with your spear. If 45 minutes is too long to wait, try leveling up Ark. Ark at level 26 can take off about 40HP whereas a level 21 can only do a few each hit.
Eventually she will be destroyed. You'll return back to the dungeon. Talk to the guy who is huddled into the corner and he'll say his name is Columbus. Columbus says he had been tortured because he was to blame for the queen sons' deaths. You'll then return to Litz. At Dr Emilio's Hospital, Columbus says that he has taught the local sailors his navigation techniques so they can sail the ocean. Dr Emilio says that Columbus needs some sleep, so talk to the nurse outside in the waiting room.She will give you the Fever Medicine. Go to the Inn for the night.
In the middle of the night, Ark is awakened by Lady Fyda. Fyda says some people are trying to kill Princess Elle and so she's putting her on the next ship to the new continent. Fyda asks Ark if he would escort the Princess to the new world. Tell Fyda that you will take the Princess to the new continent. Fyda leaves so you can get back to sleep.
Before you leave to go to the port of Litz, you may want to go back and visit Loire. The town has grown incredibly large since Jean and Louis took over. Talk to Matis and he will ask you to take one of his paintings to try to sell somewhere, and at Madame Poille's Marily gives you some Fancy Clothes that she has made in hopes that someone will want to buy more clothes from her.
