What is "oshtur"

Oshtur is a fictional character published in Marvel Comics. The character is depicted as an Elder Goddess born from the Demiurge sometime billions of years ago. Unlike her siblings, Oshtur had a fascination with the realms beyond Earth. She took to the heavens before the fall of the Elder Gods and their degeneration into malevolent demons. It is unknown for how long Oshtur left earth, but it is presumed to be millions of years. While exploring the universe and other planes of existence, she met a companion in the mysterious but immensely powerful mystical entity Hoggoth, one of the founders of the later Vishanti. Again, it is unclear when or where Oshtur and Hoggoth discovered each other, though it has been confirmed that Oshtur asexually spawned Agamotto from one of her tears.
