Spirit World is a special area accessed from Mars, and can eventually be accessed from Enemy HQ too. To access it, you must complete the Exiled's quest to open a portal to the Spirit World. The portal can only be seen if you have equipment that allows you to see spirits.
Like Death’s Door, the top of each ladder is a lava tile which ignores defense; you will lose 10 health if you don’t block it. Shield yourself as you climb up or down to block the burn damage.
The Spirit World is not a dungeon (it is not even underground); attempting to use a Book of Return will not bring you back to Mars. However, you can build a resting place to save your game here. Additionally, there is room to build a storehouse on the wider platforms; you can buy a Spirit Storehouse Seed and use that as your storage, as well as connect it to any Spirit Storehouses you plant anywhere else. In theory, you can stock the Spirit Storehouse with food if you do not have a Bunker, House, or Evo Magic House to replenish your heath for you. You can also put Focus Gems in your Spirit World storehouse, to quickly transfer to your inventory if you need to change the elements of equipment or Spirit Tree Seeds. Placing a Mini Synthesizer in front of or next to your Spirit Storehouse door will let it access the storage so you don’t have to refuel from your inventory when you need food.
Aside from the path you initially open with the help of The Exiled (the upper left), there are three other paths of interconnected platforms leading off the central hub; the lower left can only be connected with a staircase/ladder if you fulfill a quest for the Spirit, and leads to Enemy HQ. The upper right leads to a distinct Ice-element section with Ice Bushes, while the lower right leads to the only chest in the Spirit World.
An ice-element Spirit Tree grows on the last platform of the upper right path; you can harvest it for ice Spirit Arrows if you do not accidentally burn it down while cutting it. Several other platforms are suitable for planting four Spirit Trees of the other elements so that you have arrows for any enemy. Note that Spirit Trees cannot be planted if a platform above is too low,; the trees will not be able to grow to full height. Any Spirit Tree Seed except Plant element must be changed with a Focus Gem from your inventory (or vehicle inventory while mounted). Spirit Arrows are very helpful if you have either the Bow or Recurve Bow in your inventory to shoot them with, as they will home in on the nearest enemy in any direction and pierce through additional enemies nearby. Melee attacks may put you danger of counterattack from the faster and stronger types of enemy spirit, which can retaliate with high damage.
No enemy spirits spawn on the large central platform where The Spirit resides. However, the Spirit Fish may fly over and attack you. Blocking with a Book of Shielding (recommended over an Interstellar Broom because it protects you from all directions) and walking past the Spirit Fish will get it to move on in the direction it was headed and keep you safe from its powerful bite attacks.
One more way you can take advantage of the Spirit World’s geography and make a home there is to plant a Monolith from The Depths on the upper platforms, where the Monolith has the vertical space to grow. You will be able to teleport in directly, instead of going by way of airless Mars or the dangerous Enemy HQ.
If you're in the Spirit World and have no equipment that allows you to see spirits equipped, everything will become dark. This is only a visual change, and you can still do anything you were able to do with spirit vision. Another unique feature of the Spirit World is that flying is impossible, no matter what flying equipment or vehicle you have. These aspects of the spirit world can also be seen in the Colosseum.

NPCs[]
The only NPC in the Spirit World is the Spirit NPC. It acts as a shop for not only items, but also information about spirits, them, etc. The Spirit doesn't accept money as payment, instead asking for Spirit 
. It also gives you a quest for more Spirit to access a new part of the Spirit World, and to connect the Spirit World to Enemy HQ.
