Abd al-Hazir wasn’t just on the website, he’s heard in the game, as the author/narrator of many of the monster lore entries mostly from Act One. (Exceptions are mostly due to Bliz shuffling monster locations during final development. Details in comments.) He’s only lightly heard in the game beyond Act 1, and his last entry (#42) was a grim tale of running for his life after spying on a horrific Cultist ritual. Widely presumed dead, Abd al-Hazir has staged a miraculous return to the game, appearing as a chatty NPC who you can rescue during an event in the new Act Three area, the Ruins of Sescheron.
Some players have asked spoiler warnings about the new content in Patch 2.3, so click through if you’d like to see screenshots of Abd and more details, including his dialogues when encountered.
Abd is found in a random event in the new Ruins of Sescheron area. He’s locked in one of those iron cages you first see in and around Alcarnus in Act II, and surrounded by a great number of the arctic goatmen found in Sescheron. After they are killed his cage becomes clickable and he gives the following intro speech, and then has a second dialogue chain, all delivered in his self-aggrandizing style.
He follows you around the Ruins of Sescheron once you rescue him, but does not make the trip back to town when you leave the area, and is not seen afterwards. (Some commenters say the saw him in town, but he was not clickable there.) I didn’t notice, but apparently al-Hazir does provide a new Sescheron lore entry as well.
It’s possible we’ll see more of him once Patch 2.3 goes live, since the PTR might not have the full lore/story content.
