An extremely powerful application of the magical control over the element of Air is summoning lightning bolts. Merlin first cast such a spell on the Isle of the Blessed, where is powers of creature of the Old Religion were heightened. He was able to master the power over life and death and did this to strike the priestess Nimueh in order to restore the balance of the world through her death. By raising his hand, he gathered the clouds above his enemy and summoned the gods to strike her with incredibly powerful magic (Le Morte d'Arthur).
