Gaia:
Gaia is a massive planet covered by wide oceans that emanates powerful and mysterious magical energies. Though most of Gaia is covered in water, it also has occasional large portions of land, generally known as continents. The planet's magical nature makes its many continents vary wildly in several regards, from their geography and biodiversity, to their culture. You can essentially never expect two continents to be very similar to each other.
One of them has an incomprehensible amount of rivers and lakes and such, with incredible aquatic biodiversity, while another has terrifying creatures walking around its land, inspiring many horror-centered stories and art from its population, while another is notable for its many technological advancements, and so on.
At the end of the day, the life in Gaia is one of its most important aspects, and its life forms are capable of developing a psychic ability called Daydream.
Daydreams:
A Daydream is a psychic ability originated from the combined power of one's psyche and soul, being usually controlled by the mind. Daydream abilities are incredibly varied, going from powerful elemental abilities such as fire or ice-based ones, to more abstract or practical ones. While a person's Daydream can be similar to another's, no two Daydreams are entirely identical.
Throughout history, many kinds of creatures have been recorded as being able to use Daydreams. Seeing a being capable of utilizing their Daydream is generally considered uncommon for sapient species such as humans and elves, rare for animals and extremely rare for plants, fungi, microscopic beings, etc.
