Path of the Renegade

For millennia, Asdrubael Vect has ruled the dark city of Commorragh, crushing any who dare to cross him. His reach is long and his position unassailable... or so he thinks. Yllithian, an ambitious archon with the desire to unseat the tyrant, joins forces with a twisted haemonculus in an attempt to revive a long-dead warrior and challenge the might of the overlord, both racing to achieve their goal before Vect discovers their treachery. But a cataclysm is coming, and Yllithian’s actions may in fact be the cause...

 * The Dragon: Yllithian finds himself in this position.
