Question: Vala is a character that is mentioned in the world created by what English author?

full_context: Document 1: Anunnaki: The Anunnaki (also transcribed as Anunaki, Anunna, Ananaki, and other variations) are a group of deities that appear in the mythological traditions of the ancient Sumerians, Akkadians, Assyrians, and Babylonians. Descriptions of how many Anunnaki there were and what role they fulfilled are inconsistent and often contradictory. In the earliest Sumerian writings about them, which come from the Post-Akkadian period, the Anunnaki are the most powerful deities in the pantheon, descendants of An, the god of the heavens, and their primary function is to decree the fates of humanity. In "Inanna's Descent into the Netherworld", the Anunnaki are portrayed as seven judges who sit before the throne of Ereshkigal in the Underworld. Later Akkadian texts, such as "The Epic of Gilgamesh", follow this portrayal. During the Old Babylonian period, the Anunnaki were believed to be the chthonic deities of the Underworld, while the gods of the heavens were known as the Igigi.
Document 2: Old Ones (Buffy the Vampire Slayer): In the Buffyverse, the Old Ones are the extremely powerful, pure-breed demons that once dominated Earth before humankind appeared. Illyria is one of these demons (though its real form was revealed only in an illustration) while it's more than likely that Jasmine and her kind (The Powers That Be) ascended to their higher plane because of the growing malevolence of these warring demons. It's also possible that the Powers that Be were part of the same race but shared a different philosophy than the other Old Ones.
Document 3: Vala (Middle-earth): The Valar (singular Vala) are characters in J. R. R. Tolkien's legendarium. They are "gods" or "angelic beings" subordinate to the one God (Eru Ilúvatar); they are the most powerful of the Ainur who chose to go into the World (Arda) and complete its material development after its form was determined by the Music of the Ainur (Ainulindalë). For this reason they are also referred to as "the Powers of the World." They are mentioned in "The Lord of the Rings", but were developed earlier in material published posthumously in "The Silmarillion" and "The History of Middle-earth".
Document 4: Eru Ilúvatar: Eru Ilúvatar is a fictional character in J.R.R. Tolkien's Middle-earth legendarium.

The names appear in Tolkien's work both in isolation and paired ("Eru Ilúvatar").
Document 5: The Lord of the Rings: The Lord of the Rings is an epic high fantasy novel written by English author and scholar J. R. R. Tolkien.

Document 6: Loa: Loa (also spelled "lwa") are the spirits of Haitian Vodou and Louisiana Voodoo. They are also referred to as "mystères" and "the invisibles" and are intermediaries between Bondye (French: "Bon Dieu", meaning "good God")—the Supreme Creator, who is distant from the world—and humanity. Unlike saints or angels, however, they are not simply prayed to, they are served. They are each distinct beings with their own personal likes and dislikes, distinct sacred rhythms, songs, dances, ritual symbols, and special modes of service. Contrary to popular belief, the loa are not deities in and of themselves; they are intermediaries for, and dependent on, a distant Bondye.
