Islets are a Game System in Petit Planet.
Islets are the main exploration content of Starsea Voyages. They are instanced zones, typically focussing on a specific Creature type, Item, or will feature a puzzle that can be completed for extra rewards.
[WIP] Every Islet, no matter which type it falls under, will feature 
Wandering Star ×1-5 and a Chest that will award 
Tree Sap, and may contain certain Furniture. - No longer accurate as of the Final Beta. Trees and Crops can give you seeds for the trees/crops on the Islet.
Each Islet will initially be Unknown, notated with a " ? " icon, however upon exploring an Islet, its name and core type will be revealed, and can be returned to at a later date.
When visiting an islet for the first time, it is possible for players to come across an "Encounter", which can either be a new Neighbor to be invited, or an already-invited Neighbor, who will offer a reward once spoken to. After leaving an encounter, players can visit the islet again to reveal a permanent resource islet.
There are several zones where players can choose to start their voyage. By default, Players who chose Hexia as their planet will have Hexia Zone H83 unlocked, while those who chose Taffeh will have Taffeh Zone T31 unlocked. Players can unlock and explore the other starting zone by visiting a friend with the opposite planet first.
[WIP] Season Areas are locked behind a seasonal quest.
As of the Final Beta, all Zones have 3 First Encounters and 12 Islets
