The Coven is actually a remnant of what was once known as the Triune (the ancient religion seen in Diablo: The Sin War trilogy)

Adria was born in Kingsport — curiously, the southern port of Westmarch — where Reaper of Souls takes place.

Adria’s father was Sevrin — a powerful merchant in Kingsport, who strangled his wife in a fit of rage.

Adria possibly killed her own father some time later when an unusual fire burned their home. She fled north to the Westmarch capital. Joined a group of witches. Turns out Adria and Maghda met there in their youth. Years later, both witches joined the Coven and took control of the group after killing its leaders.

Adria later departed the Coven after a schism with her partner — around the time of the Darknening of Tristram.

On one of Cain’s notes, he acknowledges after taking Leah as child with him, he began to research about Adria. He decided to keep what he learned a secret, and hid the truth to Leah.

I’m surprised this book has a long timeline similar to Warcraft’s. Also most of these Leah’s notes dating Diablo III (Caldeum and Bastion Keep) are written in 1285 Anno Kehjistani. Some notes are denoted as “1st day of (what seems like a month)”. Examples: Ratham, Kathon, Ostara.

Short descriptions of each important human, angel and demon throughout history (alive and deceased).

Zoltun Kulle was from the Ennead mage clan — group which delved into transmutation and enchantment magics.

The Black Soulstone was a profane simulacrum of the three soulstones Tyrael gave the Horadrim years ago.

Now we have another name of the first Horadrim group: Jered Cain, Tal Rasha, Zoltun Kulle and Iben Fahd. The latter was among the few survivors who attempted to defeat Zoltun in his lair.

The first part was Adria and Zoltun Kulle. The third part is from the point of view of Tyrael. He expresses how he feels as a human. How he felt as an Angel and how he viewed the flaws of the Angiris Council.

“I deliberately took on the form of a mortal, sacrificing my angelic essence, in response to the Council’s continued inaction. In doing so, I hoped to set an example to the Heavens — to prove that laws can be bent for a greater good.”

Tyrael left the Heavens after Diablo the Prime Evil was defeated. He couldn’t bear the angels’ judgment — who blamed him for the countless deaths of angels. I think this is the first time we ever hear how angels are born. Tyrael mentions before he left back to Sanctuary he witnessed the Lightsong — the creation of new angels. The angels tune their essences into the Crystal Arch in synch. The harmony of this “sound” and “light” creates new angels.
