All characters have aspects, which define their capabilities and nature. All aspects fit into one of the three categories of forces, and adding up those aspects gives a base rating for each. The aspects themselves may have additional effects or open up specific powers.
Aspects can be compelled in certain situations to allow certain checks or to give a bonus in certain situations. To compel your own aspect, you can spend a fate point or an essence.
All character types except Remnants have core aspects for each category. These tend to have broad interpretations for applicable compels, allowing specific checks. This is especially true of basic physical actions and body/vessel aspects or of specific actions relevant to role/profession aspects.
Skill aspects are a special type of specialized aspect. They give the character a universal +1 for all checks involving that skill.
Song aspects give access to specific powers. All have an essence cost to activate.
Attunement Aspects give access to specific powers. Some are always on, some alter existing aspects such as an Angels resonance, some alter other checks.
Here are some examples of what some of these aspects would look like for different characters
