Tempest

The demon Tempest was banished to a neutral environment that he can only leave on the night of Aeolus. Tempest commands a quartet of big human-looking demons with the ability to drain the powers of Elementals or witches. If the powers can be collected from four Elementals by the night of Aeolus, they will transfer those powers to their master, and he will be able to control the weather all over the world.

Tempest has been vanquished by the Charmed Ones and the Elementals in the novel The Brewing Storm.

Aeolus
Aeolus is the Greek God of Wind. Once every century the planets align in such a way that it causes the winds to shift and the climate to change; this is called the Night of Aeolus. During that period, the weather becomes unstable and the earth begins to shake as the world falls out of balance. On the night of Aeolus, by the light of the full moon, the elements must come together to set everything in its proper place. To do this, a Firestarter has to gather other Elementals at the Circle of Gaea to perform the Ritual of the Guardians. If the ritual is not successful, the weather will continue to wreak havoc and could eventually tear the world apart.

Elementals use their emotions to control the elements. They can be firestarters, waterbearers, windwalkers and earthshakers.

If the Elementals use the ritual to divert the power of the elements to the demon Tempest, he will be able to control the weather and the very earth itself.
