At certain times, the runes can give men immense powers. The power they provide is magic. Each rune provides four
magical powers. But, the great ancient magician Crowley, found a method of surpassing teachings. If two souls are
united, two runes are united, and their ultimate power is unleashed, a power greater than the sum of the parts is
generated. The union of souls means that two runemasters apply their magic almost at the same time.
The union of runes refers to harmony. In other words, Fire and Earth, Earth and Wind, Wind and Water, Water and Lightning,
Lightning and Fire are harmonious. Ultimate power means the release of the maximum runic magic.
