He is awesome
Abd al-Hazir is a lore enthusiast and adventurer, scribing about a lot
of his experiences in the world of Sanctuary. He is used as a tool for
Blizzard to describe Diablo lore on the official Diablo III webpage.
The Writings of Abd al-Hazir are well known in the civilised parts of
Sanctuary. They seem to both be named works as well as a collection of
entries, such as a diary.
Abd al-Hazir is a renowned gentleman, historian, and scholar. He has
recently taken up the unprecedented task of investigating,
researching, and compiling information about the unique locales and
denizens of our world. All the character classes, monsters and
locations are introduced in the official site as parts of his journal.
Abd al-Hazir's writings are composed of 42 entries, each one detailing
a monster, a location or a class. One description for his writings is:
These pages host a collection of writings about this world known as
Sanctuary; they are intended for readers who, like the author, are
steeped in the arcane traditions. They paint a vivid picture of some
of the foulest, most accursed places and creatures you may encounter
on your travels. May the knowledge contained within guide you through
the darkness that lies ahead...
I am Abd al-Hazir, adventurer, scholar, and researcher. I share my
knowledge of this incredible world and its creatures through my
insightful missives, often at grave risk to myself. Why, I was
recently in Khanduras, where my tents were ransacked by vicious quill
fiends! I was able to beat them off with a shoe, but a less bold man
would've been fared for worse.
