Yrianox
In the final battle against the forces of good, when Alstrapath the Necromancer and the Unholy Trinity finally slew the Wizard King, it was Yrianox who dealt the killing blow, though he did it using Thakralos as a puppet. The Wizard King now dead, there was little to stop Alstrapath, Yrianox and the Unholy Trinity from decimating the world.
By joining not only in force, but in mind, Alstrapath, Yrianox and the Unholy Trinity actually became the embodiment of Mordechai, though lacking the last six shards of Mordechai's mind, were not as powerful as they might have become. In the battle against Ishmæl however, Yrianox separated himself from the gestalt when the final blow was dealt. Retreating to his lair, he remained quiet for many generations. Now, as Shædor rises to power, Yrianox has come out of hiding to serve the son of his former self.
The two fragments of Mordechai's soul which allowed Shædor to summon up Yrianox were found in disparate places. One was held by the vigilante organization Wyvern, though they had no idea what it was they had in their possession.
The second fragment was found in a Legacy Chain lair, hidden away among a series of tomes of knowledge. While the Legacy Chain had some idea of the object they possessed, they had little comprehension of its power. Shædor took the fragment for himself and used it to bring Yrianox, the undead sorcerer, to life.
Shædor now searches for the final fragment, for when he finds it, it will reveal all the secrets of the Book of Numbers, the text which reduces all of Creation to mathematical formulæ and which will allow Shædor to dominate not only this world, but all worlds.
Malechai
Not long ago, Shædor, while searching for artifacts among the Circle of Thorns wizards, found a talisman which allowed him to summon up a servant from a fallen minion by extracting what little of its soul was left, and creating a pathway for Malechai to enter the world of the living. Unfortunately, Malechai was only able to sustain himself for a short period of time, after which he discorporates.
Originally, Malechai was the adopted brother of Mordechai, Shædor's father. Malechai, the younger brother, was not as intelligent as Mordechai, but he was more ruthless and was completely devoid of even the tiniest hint of mercy.
Malechai was Mordechai's primary servant, and as such was privy to a great deal of the warlock's knowledge. When the necromancer deciphered the Book of Numbers and discovered the power hidden in the mathematics of the foundation of the Universe, Malechai tasted both the power and the madness that Mordechai's learning had uncovered.
His soul now, extracted from the fallen Shards of Mordechai, knows no fear or joy, only hatred of all living things.
Mordechai
The heavens now quake with fear, for Shædor has discovered the penultimate Shard and has combined it with four others to bring his father, the dread Lich Mordechai, back to the world of the living.
Mordechai, fragmented by madness is now made nearly whole by the collected Shards of his fragmented psyche. Only Ishmael, the Lord and Master of the Paladins was able to stand against him, and now that Ishmael is dead and gone, nothing stands before the union of Mordechai and Shaelig;dor and their complete domination of the Rogue Isles and utimately, the world.
Armed with powers even Shædor does not completely understand, Mordechai is beyond mortal ken, and is thus unpredictable in the extreme. A faction of Arachnos now watches Shædor, attempting to learn his long-term plans and determine if he is a threat to the Arachnos organization or even to Lord Recluse in particular.
