Mandate Spawns were like instances of programs that could function by themselves while drawing energy from the Mandate Root of the incarnation they belonged to.
They differed from Energy Formations because they could function by themselves almost as if they were alive and had consciousness, even at the lowest levels.
They could do all sorts of things.
An example is a Mandate Spawn that makes the incarnation it belongs to seem more attractive to others by affecting their wills. Another example is a Mandate Spawn whose sole purpose is to watch over someone wholeheartedly, noticing everything they do and reporting to the incarnation.
The more powerful an existence was, the more powerful their Mandate Spawns were allowed to be because the only thing that held back the power of a Mandate Spawn was the energy expenditure it brought about in the Mandate Root.
