Sinnoh League
An expert-level Pokemon League challenge. Navigate through volcanic peaks, glacial chasms, and desert oases to face the toughest trainers.
Complete region route
Follow Sinnoh League in verified order
Carry healing, capture supplies, and the materials shown on the next trainer card; use the Trainer Card to confirm the active checkpoint. The region route below verifies the Cobbleverse trainer chain while the selected card provides the exact locator, roster, loot, and interior path.
Ordered checkpoints
Checkpoint-to-checkpoint transitions
Pedro → Gardenia
After Pedro, use Gardenia's card for the Grass locator and review its building path before leaving your supply base.
Gardenia → Marzia
After Gardenia, complete any required Team Galactic state shown by your world, then prepare Marzia's locator and roster plan.
Marzia → Omar
After Marzia, open Omar's card, gather the Water locator recipe, and prepare for the next rise in roster level.
Omar → Fannie
After Omar, use Fannie's Ghost locator and bring a party that does not depend on one fragile type answer.
Fannie → Ferruccio
After Fannie, build Ferruccio's Steel locator and check held items and coverage on the full card roster.
Ferruccio → Bianca
After Ferruccio, collect Bianca's Ice locator materials and prepare for the Glacial Chasm route described on her card.
Bianca → Corrado
After Bianca, open Corrado's card, craft the Electric locator, and account for its chain-maze interior before the battle.
Corrado → Aaron
After Corrado, resolve the ordered Team Galactic Wind Plant, Eterna Building, and HQ dependencies your world still requires, then craft the Sinnoh League locator on Aaron's card.
Aaron → Terrie
Collect Aaron's room loot and continue inside the same League building to Terrie.
Terrie → Vulcano
Continue from Terrie's room into Vulcano's fire arena and collect the visible side loot before the battle.
Vulcano → Luciano
After Vulcano, remain inside the League, restore the party if possible, and follow Luciano's card through the next wing.
Luciano → Camilla
After Luciano, restore consumables and held items before Camilla's level-100 Champion roster and final-room unlock.
Preparation shifts
Recheck the party before the later gyms, before the Team Galactic dependency chain, and before entering the shared League building. The Elite Four and Camilla reach the endgame level band; compare all six roster slots instead of preparing from the headline type alone.
If progression stops
- If the next trainer is unavailable, confirm the previous visible checkpoint and any Team Galactic prerequisite recorded by the relevant location guide.
- Complete Team Galactic in the evidenced order: Wind Plant (Mars), Eterna Building (Jupiter), then HQ (Saturn/Cyrus). Do not infer mainline-game requirements.
- The source folder is named camila while the trainer ID and public checkpoint are sinnoh_champion_camilla; the parser preserves that guideSlug mapping.
Completion and related routes
Defeating Camilla completes the authored Sinnoh chain and reaches the documented level-100 endpoint. Continue with optional legendary, structure, team-building, and collection goals rather than inventing an undocumented fifth regional league.

Materials Checklist
Materials Checklist
Find the Sinnoh League
Head into Desert Oasis and follow the Sinnoh League search result until you find the shared Elite Four building.
Enter the League Lobby
Once inside, you will reach the main Sinnoh League interior. Check the right-side shop area before moving deeper into Aaron's section, since there is a Pixie Plate on display there.
Loot the Side Room Behind the Shop
Behind the shop area is a side room with several useful pickups. The barrel between the cobwebs contains a Dread Plate, and the barrel underneath the upper middle barrel contains Exp Candy.
Climb Up to Aaron's Wing
Take the stairs upward toward Aaron's side of the league. The pots along the way contain Trial Keys, and the room at the top of the stairs is worth checking before the battle. At the far left end of the hall, there is another room with a Legend Plate.
Battle Aaron
Aaron waits on the opposite side of the hall. His entire team is level 82:
Collect the Room Loot and Your Reward
Before or after the fight, make sure to grab the Insect Plate from the display case and the Bug Tera Shards from the barrel high above Aaron. Defeating Aaron raises the Sinnoh level cap to 87 and unlocks the path to Terrie.
