Adventure Mode
Adventure mode is Gadvia's story mode.
Islands
Currently, there are two islands available: Rayyon and Siliq. While Rayyon is free, Siliq costs 1000 
Blue Crystals. Gadvia's story is mostly separate between islands; you can play them in any order and the story will still make sense.
Most things, such as items, upgrades, equipment, Island Level, story progression, etc. are separate between islands. However there are some things that are shared between all islands:
- Currencies (
Gold Coins, Blue Crystals, 
Musical Stardust, File:Gadvia-Moonstones Icon.png Moonstones) - XP Stones (
Small XP Stone, 
Medium XP Stone, 
Large XP Stone) - Boost Vouchers
- Missions and mission progress
- Some characters (Limnoreia and KP-61) and their experience levels, stamina, and work. (note that a character's equipment is not shared between islands)
