The twilight woods are a biome in skyward.
Flora: magic grass, magic bushes, mageweave trees, sporeshroom (hostile), trapa (hostile), aeolian grass, chilling grass.
Fauna: fungus beast, centaur, gargoyle, cobalt gargoyle, nian, shadow leopard, emperor scorpion, fire spider, winged serpent, gem spider, giant claw mole, mantis, petroleum slime, zombie, skeleton.
Dangers: Pretty much every living thing here wants you dead. In the caves, zombies, skeletons, emperor scorpions, and sporeshrooms can spawn. Lower in the caves winged serpents spawn to terrorize you with their poison spit. Fire spiders roast you alive, nians just kill you, and shadow leopards will hunt you down. The trapas fling blinding purple gas clouds of death. So, yes everything here wants to or will kill you.
The resources here are very useful to have in bulk. Magic wood and mageweave bark are from the magic trees. The magic dirt is used to grow magic berries in farms, and the grassy version can generate magic grass. It has clay and soul sand veins throughout. There are many blobs of magic gems in caves or you can mine for them. in caves aeolian or chilling grasses grow.
