(A brief digression:
The Whispering Way does not have leaders. Oh, they say in Pharasma’s churches that it’s the cult of the Whispering Tyrant, seeking to restore Tar-Baphon to the dominance in Ustalav he once possessed, but in fact it’s really more of a mutual assistance group for necromancers, swapping spells and trading tips on how to best animate dead so they know how to fight, bind ghosts to obey instead of tear your throat out, and dodge the paladins and witch hunters that are the perpetual bane of Ustalav. Nonetheless, there are Whispering Way members who other members are, perhaps, more inclined to listen to than others. Being a lich helps.
So does having been an Emperor of Taldor. They call him Remek Czaszar, now, for his last subjects were savages, but there was a time he was Emperor Taldaris II, and every knight from the Arch of Aroden to the steppes of Kelesh gave him homage, and - thus he told himself - he was a just ruler, wholly worthy of his name, a monarch wise and good, a conqueror and a lord feared and respected. Wizardry he had pursued in his youth and wizardry he pursued after the throne was his, to continue his rule forever and so break the laws of eternal civil war that were the doom of Taldor. But, for some reason, when he became a lich, oh no, every Good and half of the Neutral churches in the entire Taldane Empire joined his generals to pull him down and replace him. Being a lich, he survived this, and being a lich, he has spent the past three thousand years attempting to retake the Empire of Taldor against the concerted opposition of basically everyone else in Avistan, plus the Kelesh Empire, and while he’s retaken his throne before he’s never managed to hold it.
His attempt before last involved acknowledging the Whispering Tyrant as his overlord, which is why since the failure of his last attempt some four hundred years ago (involving the creation of the small but thriving nation of Videk, east of Galt and Taldor, as an accidental byproduct) left him withdrawing to a secret fortress in the Hungry Mountains warded against all detection, there to wait out his enemies while he rebuilt his strength; hidden in his fortress are deadly traps for any intruders who dare to approach it, stockpiles of weapons and armor readied against the day of his return, legions of the undead unaging until the day they are to be unleashed, and a fanatical cult of disciples, who study his ways so that they may one day approach his glory.
He’s not the leader of the Whispering Way. It doesn’t have a leader. He’s not even one of them. But of the “the Whispering Tyrant has failed us and instead of awaiting his return we should now unite under a new leader to establish a necromantic dominion over the continent” subsubfaction, he’s one of the three or so candidates most frequently brought up as a potential leader, though those three are not really a majority when combined unless you eliminate “ME!!!” from the list of candidates.)
