The Three Dark Sisters are part of nearly the third generation of gods in Teyvat, in the same line of The Solar Chariot and the Moon Sisters, and thus their power is a direct gift from Almighty Phanes' Shining Shades. They are regarded as having primordial blood. Nonetheless, akin to their duties, their prowess and power differs one another.
Odin's power, the oldest sister, can be regarded as flexible, transformative, shapeless. In order to harvest as many souls as her divinity can, her influences have reached beyond common imaginary. As warfare is always in her dictionary, her Valkyries aid in her duties, and she holds control of most of Death's gifts.
Freyja's power, the middle sister, is the most aggressive of them, the most damaging. Her punishing methods are always effective and lethal, beauty and wisdom are pretty much some of her many weapons, and her contact with humankind had made her versed in a myriad of spells, enchantments and witchcraft.
Hel's power, the youngest sister, is wide and overwhelming. The Realm of Helheim resides beneath one of Irminsul's roots, the path known as Helway connecting the Underworld with Teyvat. Helheim is an enormous place, filled with silver rivers, great walls and infinite doors, misty valleys and the Dark Sisters' Thrones. Although it was place originally given birth by Father's power, it is now sustained mainly on Hel's. Her energy surpass those of her sisters combined, with the only purpose of protect Helheim's Gates and Realm.
