Editing Durgaz's Stuff he knows (section)

====The Night Kings====
Directing the occupation are Izrador’s lieutenants, the
four dread Night Kings, immortal creatures that were once
champions in the fight against the dark god. 
=====Sword of Shadow=====
In the occupied
lands, the best known of the Night Kings is Jahzir, the Sword
of Shadow. Once the Lord General of all the armies of the
Kingdom of Erenland, Jahzir was captured and twisted by the
dark god, and now commands armies of darkness instead of
those of light. It was his knowledge and skill that allowed the
dark god’s hordes to slice through the already weakened
armies of good without breaking stride. He now commands
the loyalty of many of the largest orc tribes and has unquestioned
control of the orc legions. As the king of Erenland, he
has the authority to command the forces of the traitor princes
and can conscript troops from the enslaved population to
serve as fodder for elven arrows and dwarven axes. Militarily,
he is unchallenged by either the Order of Shadow or his fellow
Night Kings. He often rides abroad with his armies, but
also holds court from his palace in Alvedara and is known to
frequent Theros Obsidia; wherever he goes, however, he
seems to relish his control over the kingdom he helped to
destroy, and does all he can to bleed its shattered remnants to
feed his armies.
=====Sorcerer of Shadow=====
Possibly the most dangerous and least known of the
Night Kings is the Sorcerer of Shadow. 
=====Priest of Shadow=====
Controlling the dark god’s legates is the Night King
known as the Priest of Shadow. This gaunt figure, once
believed to be a Sarcosan holy man, is responsible for the sacrifice
of tens of thousands to Izrador each year. He is reviled
in the Sarcosan south for turning the once vibrant city of
Cambrial into a vast necropolis. Rumors of his creations,
including creatures built from the remains of man and beast
and legions of undead soldiers marching to war, are told in
every town and village south of the Ardune.
=====Wrath of Shadow=====
The most savage and openly destructive of the Night
Kings is the mighty dragon known as the Wrath of Shadow.
Thankfully, this creature is rarely seen outside of Highwall or
above the battle lines of Erethor. Where she goes, destruction
follows, and few live to tell of her attacks. The fey call her the
'''Scar’garath, “doom of Erethor”''' in High Elven. The dragon is
the most powerful creature on Eredane and there is no hero
left alive who could withstand its terrible power.
