Hello, using an AI I was able to summarize CZ characters in one sentence. Here they are.
Melkor: Return and Dagor Dagorath The thousands of years before his return were anxious years, all looming under the imminent threat of this menace's return.
Nameless One: Ruling the Heavens Nameless one ruled the heavens since the creation of Ea and judged many trials.
Pythas: Accal repeatedly bested his father, first when Accal fought Pythas' wolf form, at first Accal had no knowledge that Pythas was his father, since he did not recognize his form as The Night Wolf, but eventually he realized that his father was Pythas.
Snowfalls: Snowfalls bore the life force of the entire Ice Army all but the King of Ice, Raegon.
Glarthir: Assisting in the Ice War Other than finding the wrong Chosen One, Glarthir assisted in the ice war in other ways.
Nook: Impact of Orome's Death Orome appeared to be a father figure to Nook as he was more of a father to Nook than what Mairon ever was.
Orome: Orome being locked in the Gold City by Pythas Forest Annihilated After Orome was free from Gold City, he found the forest to be greatly changed from what it had been.
Manwe: Banishing Melkor Manwe assisted in the banishment of Melkor from Arda a total of two times, both times to different places.
Varda: Elbereth was able to see into Melkor's mind and she hated him, causing Melkor to be afraid of Elbereth.
Mandos: Lord of Law Valinor, the high interstellar court and the lesser courts were subject to Mandos and his law firm.
Tulkas: Tulkas chaining up Melkor, Tulkas did eventually return to Arda after Nameless One departed.
Aule: Aule went to destroy the race of dwarves after Eru expressed dissatisfaction with Aule's actions.
The Witch King: A Shocking Revelation Despite Amir desiring to have a son with Loki, it would eventually turn out that Amir had already had a son long ago.
Raegon: Glarthir the Ice Child had prophesied their return during Winter, which was far away, so everyone had to wait and see if Raegon and the Ice Army would return.
Ungoliant: Ungoliant and Melkor Two Trees of Valinor Working under Melkor's instructions, Ungoliant drank the light from the Two Trees of the Valinor.
Azeb: Restoring Gondolin Azeb would use his wealth to restore Gondolin.
RenJey: Pythas recruited RenJey to join him and gave him a nazgul ring, completing RenJey's corruption.
Cthulhu: It is thought that perhaps Cthulhu is a creation a Melkor that was set loose upon the seas to terrorize sailors, Cthulhu could also be a Nameless Thing, similar to Ungoliant, or even a malevolent Ainur.
Ancalagon: Taking Over On December 30 and 31st of 2021, Ancalagon and Fire Nation waged assaults on all the lands ruled by landowners that did not submit to Ancalagon.

Mikomi: Resignation On the 9th of September 2014, Mikomi chose to resign from the title of Emperor Helper and Administrator.

How did you do that?

"Aule went to destroy the race of dwarves after Eru expressed dissatisfaction with Aule's actions." WHAT?

The AI basically finds a good summary for the text it is given, and it chose that Aule's main goal was to create and then destroy the dwarves.
