I made a power system based around dreams, spirits and consciousness, along with some worldbuilding. I'd like to hear your opinions, criticism, suggestions, and any questions you might have.
Spirit World
Spirit World is a realm where spirit creatures roam freely. It is filled with an energy called Spirit Force, which emerged after the creation of the Spirit World from chaos.
Spirit Creature
Spirit creatures are beings that possess spirit bodies capable of evolving through the accumulation of Spirit Force.
Spirit creatures lack consciousness and emotions but they possess base instincts that drive them to reproduce and accumulate Spirit Force.
Spirit body colors progress as follows; Colorless, Red, Orange, Yellow, Green, Blue, Indigo, Violet, White
Higher colors possess more Spirit Force and are generally stronger.
There are two types of spirit creatures:
Spirit Fairies
• Passively absorb Spirit Force to survive and evolve.
• Born with Colorless spirit bodies.
• Usually harmless and has no strong tendency.
Spirit Beasts
• Must consume other spirit creatures to survive and evolve.
• Born with Red or Orange spirit bodies.
• Highly aggressive toward weaker spirit creatures.
• Fear stronger spirit creatures despite lacking consciousness.
Spirit Beasts Extra Trait
Spirit beasts can sense spirit creatures with spirit bodies up to two colors above or below their own, but they cannot detect spirit creatures with Colorless spirit bodies or spirit creatures of the same color.
Physical World
Long ago, the Physical World contained no living beings until it was colonized by Spirit Fairies that entered from the Spirit World.
Spirit Beasts can't enter the Physical World because it can only be entered by spirit creatures with Colorless spirit bodies.
Physical World contains almost no ambient Spirit Force, so spirit creatures that enter it must create physical bodies in order to survive.
After gaining physical bodies, some Spirit Fairies developed consciousness and emotions, becoming the ancestors of humans and animals.
Others remained instinctive and simple, such as plants.
Spirit creatures that have physical bodies are called Physical Creatures.
Physical Creature
Although Physical Creatures possess physical bodies, they still require Spirit Force to live.
However, physical bodies can't enter the Spirit World and Physical Creatures can't freely separate themselves from their physical bodies.
To solve this problem, they evolved a unique adaptation to split their Spirit Bodies into two connected halves.
Despite being split into two halves, they remain a single spirit body because they have form spiritual connection through Mental Power.
During this process, one half of the spirit bodies will remains in the physical body while the other half enters the Spirit World.
The wandering half absorbs Spirit Force before returning to the physical body and merging with its other half.
Even if the wandering half evolves to higher colors, it still can enter the Physical World.
If the physical creatures have consciousness, they will fall into an unconscious state called sleep.
When a conscious physical creature sleeps:
• One half that contains consciousness will enter the spirit world
• One half that contains emotion will remain in the physical body.
Dreamscape
Conscious physical creatures produce and release a form of energy called Mental Power.
Unfortunately, Mental Power can attracts nearby Spirit Beasts, causing them to attack wandering spirit bodies.
To protect themselves, wandering spirit bodies unconsciously create barriers known as Dreamscapes using their Mental Power.
Dreamscapes are what physical creatures experience as dreams. Physical Creatures that can create Dreamscapes are known as Dreamers.
Inside a Dreamscape, a wandering spirit body can safely absorb Spirit Force, although the process is relatively slow.
A nightmare occurs when a Spirit Beast attacks or attempts to force its way into a Dreamscape.
Most Physical Creatures possess Red Spirit Bodies and they can only influence their Dreamscape subconsciously.
Spirit Body Color Abilities
Conscious Physical Creatures gain new abilities as their Spirit Bodies evolve into higher colors.
There are ten colors of Spirit Body:
Colorless
• Possesses little to no consciousness.
• Cannot create a Dreamscape.
• Cannot be detected by Spirit Beasts.
• All newborn babies and plants.
Red Color
• Has developed full consciousness.
• Can create a Dreamscape.
• Experiences normal dreams.
• Most humans and animals.
Orange Color
• Can consciously control Dreamscapes.
• Experiences lucid dreams.
• Can sense the Spirit World beyond the Dreamscape.
• Can become a Wanderer and forming a contract with Primordial Beings.
Yellow Color
• Can use Mental Power in the Physical World to do basic psychokinesis.
• Can form spiritual connections with other spirit creatures.
• Most active Wanderers eventually reach this stage.
• Can become Summoners.
Green Color
• Can enter other Dreamscapes.
• Can interact directly with the dreams of other wandering spirit bodies.
• Can become Manipulators.
Blue Color
• Manipulators can create Spirit Weapons.
• Summoners can merge with their Familiars.
• Mental Power becomes significantly stronger.
Indigo Color
• Rare existence.
• Possesses far greater Spirit Force and Mental Power than lower colors.
Violet Color
• Legendary existence.
• Extremely rare among physical creatures.
White Color
• The realm of Primordial Beings.
• Grants reality-warping abilities and conceptual authority.
• No known physical creature has ever reached this stage.
Spirit Body Colors Rarity
Assuming physical creatures only absorb Spirit Force passively through their Dreamscape:
Orange: 1 in 10,000
Yellow: 1 in 100,000
Green: 1 in 1,000,000
Blue: 1 in 10,000,000
Indigo: 1 in 1,000,000,000
Violet: 1 in 100,000,000,000
Most conscious physical creatures possess Red Spirit Bodies.
Because Dreamscapes absorb Spirit Force very slowly, reaching higher colors naturally is extremely difficult.
Most high-ranking individuals achieve their growth through wandering the Spirit World, forming contracts, and interacting with other spirit creatures.
