Paradism

Paradism was a force that prevented time travel paradoxes from occurring. This force prevented future influence from impacting the past in a way that would prevent the future from happening (paradox). Paradism was carried by paradons, and it only appeared in situations in time travel where a paradox could arise. Beings travelling back in time could often explore the past world and never come across paradism. Paradism did occasionally appear in situations outside of time travel to prevent "future" beings from creating paradoxes in the present. Due to the extreme difficulty of time travel to the past, paradism rarely occurred.

Action
A paradox occurred when any influence from the present travelling back in time prevented that influence from happening. The most common example of a paradox occurred if a person traveled back through time and killed their earlier self, which would prevent their "present" self from having ever existed. The force of paradism would prevent this from occurring by various means, including creating a physical barrier between the "present" being and their "past" self, redirecting force (such as blades or blaster bolts) and making it non lethal, preventing the "present" being from ever meeting their "past" self or in extreme cases killing the being in their present form, and possibly even destroying the means through which they traveled back in time.

Carrier
Paradism was carried by paradons. These particles had variable mass and could carry electric charge. They had a particle spin of 6, the second highest observed after that of vions. Consequently, paradons had unusual and poorly understood properties. Those studying these forces theorized that both paradism and viism possessed incredible complexity, almost intelligence, and that these properties were caused by the high spin of their carrier particles.
