Laws & Pacts
Pacts are formed with anima (light) or darkness (shadow), which are the life force of all things.
Usually, pacts are sealed with a kiss because the anima between two souls/beings must be shared; however, there are many different types of bindings which sometimes are formed in other physical exchanges like sharing blood, engaging in battle, or sexual relationships.
Laws & Rules
Pacts will remain intact even if someone dies, as long as their promises are kept. If, however, their pact requires both individuals to be alive, their binding/pact will be severed.
The laws and conditions of a pact are decided by those involved, but it's also possible to force a pact and its conditions upon a person, such as placing a brand or seal.
