Sylva is a Terran Planet in Astroneer, with the moon Desolo orbiting it. It is the starting planet, with everything a player needs to begin their adventure. It has an average atmosphere and is very temperate and pleasant. Power generation on Sylva is balanced enough for the player to effectively use Solar panels, Wind Turbines, or Small Generators. The Medium Generator is not a reliable option because the Tungsten that is needed to fabricate it isn't a naturally available resource on the planet. However, Medium Generators can be found on wrecks underground, allowing the player access before being able to reach Tungsten. Sylva contains a large cave filled with giant mushrooms.

Gateway Network[edit | edit source]

AstroWiki Warning.svg Spoiler Warning: Information below contains information that may ruin your enjoyment of discovering the game's secrets for yourself. Proceed at your own risk.

Sylva has six Gateway Chambers, each requiring 5U/s of power for 30 seconds to be activated. At least one must be activated before the player can access the Gateway Engine in the core of the planet.

Once a Gateway Chamber has been activated, the Gateway Engine opens in the core. Placing a single Icon Quartz.png Quartz in one of the slots reveals the Geometric Triptych. Placing the Geometric Triptych in the slot on the opposite side (above you) will activate the engine, revealing the Odd Stone and allowing teleportation to the core as well as revealing the inactive node for the Gateway Portal if it has not yet been discovered.
