Caves are scattered throughout the Main Island. They vary in size as well as resources, ranging from oversized ferns and geodes all the way to white Marble and Crystal Geodes. All caves have rocks that can be mined for stone.
Access
A majority of caves are not accessible to the player at the start of the game, since big rock formations cover the entrance. They must be excavated with the help of miners after the player purchases the Miner's Camp upgrade from the Upgrade Table.
After purchasing the upgrade the player will find wooden signs in front of the blocked caves. Interacting with a sign will begin a quest prompt, asking the player to pay an amount of gold for the entrance to be cleared. Once the fee is paid, the cave will be immediately accessible and the quest marked complete in the player's quest log.
Cave Locations
Note: Caves do not have names in game. NPCs only speak about them by referencing their location ("cave under the ruins"). The only exception is in the quest name "Waterfall Cave", referring to the large cave under the waterfall, not the small one on top.
For the sake of convenience and reference purposes, caves are referred to across this wiki with the below placeholder names. The "C#" after a name refers to its location on the Detailed Map.
