The Obsidia Ward is the third ward you will pass through on your journey through the Reborn region, formerly a bustling marketplace, the ward is ravaged by various disasters when you first enter. Wriggling plants from the strange going-ons of the park are scattered throughout the streets, which are ravaged with chasms from earthquakes. Similar to the Peridot Ward, it is split up into the Obsidia Ward, the North Obsidia Ward, and the South Obsidia Ward.
The Salon is the first building you'll see upon entering the Obsidia Ward. Employees here greatly care about Pokémon's happiness, and they know a lot about it, too-One employee can tell you how much your Pokémon likes you, and another will give you a Soothe Bell if you've raised your Pokémon to be happy enough to satisfy her. A third employee will groom your Pokémon for 1500 once per day, which raises its happiness.
Located across the street from Critical Capture is an economic giant so powerful that nearly all nearby businesses went bankrupt. The Devon employees cheerfully remind you of the Devon Corp's great history, its bright future, and its present that you are strictly forbidden from knowing too much about.
Next door to the Devon Corp is a multicolored sugar craze. Children dash through (and sometimes on!) the shelves of treats that delight humans and Pokémon alike. In the back of the shop is a tile puzzle in the shape of the store's mascot, a Pokémon as sweet as their products, and solving it earns you a Swirlix of your own. This puzzle can be repeated for the same reward endlessly.
In the back of the store is a vending machine. A child stares longingly at it, penniless for her greatest desire-Chocolate Ice Cream. If you give her some, she'll happily thank you for it and leave to eat it outside, giving you access to the vending machine. Occasionally, a Blue Moon Ice Cream will drop for free after several consecutive cones have been bought, every 40-50 cones it should drop one. The price for Vanilla Ice Cream is raised up to 1000 when first accessing the vending machine. That is because it actually drops Vanillite.
On the other side of the Pokémon Center is a house with stairs leading down to the other side of the Underground Railnet, where slightly different Pokémon can be caught.
To the right of the Pokémon Center is the Day Care. However, whenever you go in and talk to the Day Care couple they will be acting strangely saying that they are "actually closed". Talking to either one of them repeatedly results in them becoming more irritated, until eventually the pair give up and reveal their true identities as members of Team Meteor. After their defeat the pair explain their scheme and admit they locked the real Day Care couple away somewhere else and hid the key somewhere else. The Warehouse Key can be found in Park after defeating ZEL and his Pulse Tangrowth, this Key opens warehouses in the Coral Ward.
A woman inside the center is concerned about her son, lost in the current chaos. Locate him in South Obsidia Ward next to the Glamzonia Salon and return him to her to receive a reward. You must solve the problems at the Obsidia Park before the boy can return to the Center.
A women is concerned for her boyfriend who got swallowed up by the earthquakes, find him in the Underground Railnet after you clear out the train with the others and she will give you a department store sticker.
After meeting Amaria in the Coral Ward, Amaria and Florinia meet the player outside the park and Cut their way inside after giving the player TMX1 Cut. Amaria and Florinia head on inside, but just as the player steps in, they hear the screams of Amaria up ahead.
As the player approaches the center of the park, they see a terrible sight: Amaria and Florinia have been captured by a Tangrowth attached to a machine by a member of Team Meteor. The member introduces themselves as ZEL. They explain that the machine is the source of all the damage throughout the town, amplifying Tangrowth's power so it can make mass weapons out of even the smallest root. They dare the player to attempt to stop it, and battle them using the Tangrowth, still hooked up to the machine. After the threat has passed, Amaria and Florinia agree that there is more to the situation than realized, and head their separate ways.
With the overgrowth removed, the park and its Pokémon are now accessible to the player.
The Obsidia Department Store is a massively tall building in the Obsidia Ward that sells almost every kind of item imaginable. However, due to not-quite-sufficient stock, patrons must have a certain number of stickers on their Membership Card to be able to access certain floors.
After getting Cut, the alleyway in the south west of Obsidia is now accessible. The alleyway holds a few hidden items, different wild Pokémon, and a few Special Encounters.
The Yureyu Building is an abandoned building located in the Obsidia Ward. Rumors said that the building was damaged by an earthquake. Later on in the game it is revealed that the building was destroyed by Team Meteor.
In the Sweet Kiss Candy Shop you can win a Swirlix by completing a puzzle. This can be done multiple times, and Swirlix beyond the first one will have Belly Drum Egg Move.
When first accessing the vending machine in the Sweet Kiss Candy Shop after giving the girl in front of it some Chocolate Ice Cream, a Vanillite will drop down instead of a Vanilla Ice Cream.
During sunny morning and daytime, Petilil can be found in the Obsidia Park, and will join the player if they have PokeSnax. Petilil is found only after beating Florinia's Gym.
In the very back of the alley at night, a pair of stray Mightyenas are ganging up on an Electrike. After defeating them, Electrike will wish to join your party, but will disappear if refused. Electrike knows a random Egg Move either Crunch, Flame Burst or Ice Fang. If you progress into the Onyx Ward you cannot complete this counter until the gym has be cleared.
There is a Litleo eating in the alleyway that will run off when approached by the player. The Litleo can then be found hiding in the house west of the pokemon center, but will again bolt at the sight of the player, running downstairs into the east Railnet Entrance. As the player corners them, a level 35 Klinglang descends from the ceiling and attacks. After defeating the Mechanightmare, Litleo will join your party.
In a small space in the alley lives a Plusle and Minun. A member of the family will investigate the player, and if they have PokeSnax, join them. The Pokémon will know an Egg Move either Wish or Sing. To get the other one, the player has to exit and reenter alley until it appears.
If the player brings Glamzonia Salon's Glameow to Central Salon's groomer, she will fight you. If you win this fight, you will receive a Bounsweet with Play Rough and Synthesis.
Beginning in the South Obsidia Ward, this is a hide-and-seek quest similar to the Teddiursa Chase. However, this Lillipup has much more stamina, and can be found in more wards.
During daytime when it is clear weather, a Spoink can be found on the path from the Coral Ward to the Obsidia Ward. After interacting with it, it will take off for a storage unit in the Coral Ward.
1500 once per day, which raises its happiness.
