A long lifetime ago, Ioannes Arsenikos -- then only the heir to a single city on the coast -- had spent a number of years in the Jade Kingdoms, studying the strange ways of the magicks that its inhabitants still claimed to possess. Nine out of every ten supposed practitioners were not mages but magicians, of course, and you were more likely to have some cretin steal your coin while watching them than to learn anything particularly useful. There had been one old man, however, who claimed to have knowledge of the ways of life and death.
"Only death can pay for life," the man had explained in the way signature of the self-acclaimed mages, his words seemingly insightful but almost entirely meaningless. But as Ioannes watched in interest the man had slaughtered a number of ugly green frogs and spent the good part of the afternoon performing strange rituals over them. Ioannes had kept a firm grip on his coin purse, but was pleasantly suprised -- if a little disgusted -- when one of the frogs regained its feet and began to amble about. And Ioannes vividly remembered how the old man had put an end to his creation when he had suitably impressed his visitor; with a torch he set the creature alight like so much kindling, and it made no sound as it burned as if made entirely of tallow.
On the streets and in the taverns sometime afterwards, Ioannes had learned something just as interesting. That old man, the locals claimed, had been a simple trickster only a few months prior, but more and more of the ancient magicks seemed truly to be awakening. Ioannes had gone on to observe another half-dozen magicians, including a supposed fortune-teller (who took his coin and told him he would be a great man) and a rather impressive pyromancer who could summon flame from the air.
Only death can pay for life. A sickly feeling overtook Ioannes as he struggled to maintain a hold on his nervous horse. He began to understand why so many half-trained armies of slave soldiers had been sent out to die from the gates, and was immensely glad to have burned the bodies when they grew too numerous to bury.
But that was not important. What was important was the battle at hand, two dozen of Ioannes' finest cavalry locked in a mortal struggle with more black-clad warriors as the dead began to pour from the hallway through which they had entered the courtyard. As Ioannes traded blows with a silent black knight, he noticed out of the corner of his eye as one of the foes cleaved the head from his enemy's horse. Beast and rider fell to the ground, the horse crushing the man, but within moments both had risen again on the other side of the battle.
There was no time to be wasted. With a lucky strike Ioannes buried his blade in the neck of his enemy, who fell to his knees as black blood hissed from his gorget. He might rise again in moments, Ioannes knew. But in his off-hand was the torch with which he had lit his way through the dark and twisting chambers of the citadel. When the knight rose again Ioannes jabbed his torch into the gash he had created. The living corpse began to smolder as though it were made of kindling, and by the time it had raised its sword once more the arm holding it was aflame. The sword-arm remained raised, billowing with acrid smoke, as the creature fell lifeless to the ground.
"Flame! Give them flame!" He wheeled his horse to look to the horseman to his right, a minor household knight. "Send word to the infantry." The knight's face was pale as ash as he drove an opening into the flow of undead. Whether the man would make it out of the fortress was another question entirely.
Across the courtyard, the nameless, almost inhuman-looking leader of this vile fortress stood, one first gestured out in silent challenge. Just to look on the strange and horrible runes that covered his armor and shield caused Ioannes' head to ache, but he forced himself to watch as he spurred his horse forward.
When they stood separated by only a few paces, Ioannes dismounted his destrier. It would only be further encumbrance in such close quarters; he could only hope that the horse would not go mad with fear and charge away. Looking back, Ioannes watched as more of the dead -- some he knew well, having seen their corpses filling the halls he had passed -- spilled into the courtyard. But for now all that existed was Ioannes and his foe. They both raised their blades.
The black knight's armor seemed to drink up the light in exactly the way that it should not have, making the entire courtyard seem a bit darker. His shield was dark oak covered in a thin layer of the same metal, graven with unreadable runes. His sword was twice the size of Ioannes', clearly intended for a large man to wield with two hands, though his foe held it with one as though it were a child's wooden training blade.
The commander seemed to have no words left to say. Instead he simply swung his blade, a brutal sideways slash that might have cut Ioannes cleanly in two had he not interposed his own weapon. There was a terrible screeching of metal, but the tempered orichalcum sword held strong. Ioannes stepped into the reach of the blade and swung at his foe's chest. Instead his sword clashed against the heavy shield. The black knight made a cold, grumbling sound that might have been a laugh as he countered, bashing Ioannes out of the inside of his sword-reach with his shield.
They traded blows several times further, the song of steel filling the courtyard as Ioannes' horsemen continued to hold off the remaining black knights and the undead horde that continued to pour in. But while Ioannes was a skilled swordsman, he was not entirely a match for this beast of a necromancer. With another savage blow of his shield he knocked Ioannes to the ground, and raised his sword to make an end of it -- but the booming, icy laugh turned into a noise halfway between scream and groan when one of the cavalrymen, riding desperately from across the yard, buried a lance to its hilt through the necromancer-warrior's chest.
