Parvati is, technically, the Queen of the Gods and Goddess of the Land and of Life. After the death of her husband Mahadeva, however, she absorbed his power over birth and death and in so doing became unstable. She is sometimes called the Fractured Goddess or the Two-Faced Lady. In her "Parvati" aspect, she is benevolent, overseeing birth and flourishing life, crops, and agriculture. In her "Kali" aspect, however, she is the terrifying goddess of death and destruction. While the educated acknowledge that those latter things are necessary, few can confront Kali without fear, although there are many secretive cults and temples devoted to her.
Although she is easily the most powerful of the gods, her unstable personality has resulted in her second son Indra assuming the mantle and authority of King of the Gods.
Parvati birthed the Ten Great Dragons at the end of the Godswar in order to bring down her rebel son Surya as quickly as possible, but also to create a powerful disincentive for any repeat of the War in Heaven and Earth. Never again does she wish to see a god or goddess destroyed, and the Dragons are her weapons should open conflict break out among the gods once more.
Parvati's original Realm was the Feywild, a place of impossible life, immense forests, playful streams, where nothing is born and nothing dies. Since assuming her husband's power, however, her attention is split, with Kali presiding over the Halls of the Dead. The Feywild is now overseen by Aranyani, the Queen of the Fae and First of the Elves, who acts as guardian and steward for the goddess.
In her "Parvati" aspect, she is typically depicted holding icons associated with agriculture and fertility or is depicted in motherly poses or environments. In her "Kali" aspect, she is blood-drenched with a necklace of skulls and a skirt of twitching human arms.
