The creation of Arett differed from the creation of other Liferealms, the main aspect being that it had two Lifesowers. Normally, a Liferealm will only have one Lifesower to create it, so as to avoid the possibility of the Liferealm imploding due to an excess of magical energy. Even if it does not implode, excessive magical energy in a Liferealm may lead to its sentient inhabitants wielding the magick and being corrupted by it.
