Arcanum Majeure

Arcanum Majeure is magic only Arcanum and Principalities can access as it is quite powerful. It involves using the body as a sigil in its own right, and the cost is life, in seconds, minutes, and years. Those who use too much Majeure, such as the Tower, are unable to rejuvenate past their youngest point, around 40 for the Tower. Companions are also affected by this limit.

Majeure involves no meditation and requires no external sigil, making it quite powerful and fast acting. Rune's sword is an example of Majeure, as he uses his own life force to power it. Power is rapidly depleted when using Majeure and can take a while to "recharge." There may be other limits to its use, but its full specifications are not known to the Tower. He postulates that it is genetic.

Rune did not learn about the secrets of Majeure until after he claimed his throne. The Arcanum do not want outsiders knowing that there are limits to their powers.
