Hel, Goddess of Death and the Underworld

Description
Hel is a deity in the Norse Pantheon. The daughter of Loki and the witch-giant Angrboda, she rules the underworld of the dead of Midgard. Hel appears as a thin woman, beautiful on one side but like a rotting zombie on the other. For this horrid visage she is outcast among the Gods, but admired by the dead. Hel's visage is frightening for mortals to view. When she reveals the undead half of her face, it inflicts fear in even the bravest of mortals.
She occasionally sends an avatar to Midgard who takes the form of a warrior-priestess with a swarthy complexion and black hair. Her avatar is often tasked with recovering a man who Hel favors and taking him to Niflheim. The kiss of her avatar causes death, and mere proximity to her is dangerous. Hel is sometimes depicted with half of her face a featureless white, and the other half black.
As a deity, Hel is immortal. She cannot be harmed by disease, paralysis, poison, stunning, magical imprisonment, extraplanar banishment, or other effects to which deities are typically immune. She can see, sense and communicate at a distance of 15 miles from herself or any of her worshipers, holy sites, or any where her name or one of her titles were spoken. She is dangerous in combat. Any opponent or object she strikes can be obliterated with a single strike. She can also drain the life from a creature by touch. She has a third power, which can surround her with a cloud of darkness which drains the life of those who enter it. A fourth power lets her instantly slay any mortal she can see, and she can raise anyone back to life too. Should anything survive these powers, her weapon attacks are especially deadly to Celestials and good-aligned Gods.
Hel is also highly resilient. Her wounds repair quickly, like the regeneration of a Troll. If slain, she will simply return to life days later. She is immune to cold and fire. Her skill with both arcane and divine magic is unsurpassed. She can cast wizard spells instantaneously. She is particularly skilled with divine necromancy spells. 
She holds power over the undead. She can instantaneously command or destroy any undead, and can summon undead as she wishes. She can inflict plague and pestilence upon Midgard with a wave of her hand. Hel can create magic items that can deal damage, or have an evil alignment, or impose a penalty. She can create all but the most legendary of magic items in this way.
