西元二世紀北歐神話裡的奧丁大神倒掛在宇宙樹上九天九夜，並以長槍刺傷了自己的左眼，而發現了盧恩符文，宇宙樹高達天際，於此樹上衍生有九個王國，中土為人類居住的世界。

位於宇宙樹最上層，阿斯嘉(Asgard)是阿薩神族的國度，位在天上太陽與月亮中間，與人類世界可經由彩虹橋相通。
位於宇宙樹最下層，海爾海姆(Helheim) 為冥界，是亡靈之國。

在中土居住的人類世界，無不受到天界與冥界的交互影響，每年由女巫若伊透過冥想，以中土元素為中心得出五個宇宙參數，在不同的時運下與盧恩符文的序列數值交互作用，分別得出天界與冥界的參數訊息，也就是『凡事皆有百分比』的運算基礎，能預知所問事件發展的可能機率，方便個人做短期的預知占卜。

不知名的吟遊詩人，流傳了一首詩歌：

            奧丁化身為信使，來回穿越異世界，
            於黎明破曉之際，賜予人類神秘的魔法，
            穆寧與胡金帶來訊息，給你所需要的或然率。

占卜方式：請參照套組中的仿單說明。

In the 2nd century of Norse mythology, the god Odin hung upside down on the World Tree for nine days and nights, piercing one of his eyes with a spear.

Through this sacrifice, he discovered the runes. The World Tree reaches high into the sky and gives rise to nine realms, with Midgard being the world inhabited by humans.

At the top of the World Tree lies Asgard, the realm of the Aesir gods, positioned between the sun and moon, connected to the human world by the Rainbow Bridge.

At the bottom of the World Tree is Helheim, the underworld and realm of the dead.

In Midgard, the world of humans is influenced by the interactions between the heavens and the underworld.

Every year, the witch Zoe meditates on the elements of Midgard to derive five cosmic parameters.

Under different circumstances, these parameters interact with the numerical sequences of the runes to provide insights from both the heavens and the underworld. 

This serves as the basis for "Everything has a %," enabling predictions about the potential outcomes of inquired events, making it convenient for personal short-term divination.

An unknown bard has left a poem :

          Odin transforms into a messenger,traveling through different worlds,
          at the break of dawn,bestowing mysterious magic upon humanity.
          Muninn and Huginn bring messages,providing you with the necessary probabilities.
