World Fraction

The World Fractions (森羅変転 or ワールド・フラクション) are global-level magic phenomenons that alter the world of Elder Tale. According to ReGan, it has happened three times in the history:

World Fractions seem to be where new races or people enter the world and are events of extreme change and importance no now knows what caused the second and third fraction, but they are able to be caused by magic as the Alv princesses were able to create one through Alv science and magic.
 * The First World Fraction (亜人間の発生と古来種の出現) happened around 300 years ago when the six scrapped princesses were about to be killed. After this event, demi-human species, including Goblin, Kobold, Ogre, Orc, Troll, Gnoll, Lizard, Sahuagin, and Lizardman appeared.
 * The Second World Fraction (冒険者の出現) happened 60 years after the first one (240 years ago). After this event, Adventurers appeared.
 * The Third World Fraction (冒険者たちの定住化) happened in May and resulted in the Adventurers' permanent residence in the world of Elder Tale. Adventurers call this event the Catastrophe. Players noticed that, unlike before, the People of the Land suddenly acquired their own personalities and stories (although it is the other way around from the Landers' perspective). Also, Adventurers are now able to use Overskills.

Shiroe's Magic Contract could be considered as global-level magic, as it is able to override a fundamental law of Elder Tale by turning a Person of the Land into an Adventurer. The potential for chaos is immeasurable, which is why Shiroe keeps this ability an absolute secret.

Plant Hwyaden's Zeldys reactivated the transport gate in Minami and has possibly rewritten how transport gates work using his Overskill, Mana Breeder, with Jered Gan's research.

Trivia

 * The Second World Fraction, when the Adventurers appeared, coincides with when Elder Tale first launched its beta version, 20 years ago before the current events took place, with Nyanta among the beta testers.
