Complete Monster: Haazheel Thorn is the single most evil being in this feudal Dark FantasyCrapsack World. As an incredibly powerful Sorcerous Overlord and the leader of the Black Moon faith, which reveres him as a demigod, Haazheel, together with Greldinard, the Baron of Moork, sends his armies out on crusades of death against the Empire of Lynn, ordering his soldiers to Rape, Pillage, and Burn all in their path. To bring Wismerhill, a half-elf half-human prophesized to play a major role in the fate of the world, over to his side, he sets up the apparent death of Wismerhill's father, then blames it on the empire to incur Wismerhill's hatred for its battered monarch Emperor Haghendorf. Haazheel sends thousands of his troops to their deaths in a futile battle against the empire to fake his own death and rebuild his forces at his leisure. Haazheel turns out to be the half-demon son of Lucifer, and plans to bring about Hell on Earth while sending as many people as possible to Hell to have their souls devoured, thus ensuring himself a seat at his father's side. The army of the Black Moon, commanded by Wismerhill, totally obliterates the Empire of Lynn, sacking the capital, killing the Emperor, and forcing the faithful few who survived to ascend to another dimension. Wismerhill is made the new emperor by Haazheel, who retreats to his palace on the moon while his demons rampage around the world and his priests forcibly convert as many people as possible to the Black Moon to increase Haazheel's power, with those who refuse being torn apart by demons before having their souls devoured. After Wismerhill learns of Haazheel's manipulations and true plans he closes the Hellgate, at which point Haazheel personally teleports down to the imperial palace with his forces to punish Wismerhill for his defiance, initiating a slaughter that Greldinard walks away from in disgust. When his forces are defeated, Haazheel assumes his demonic form to kill any living thing in sight, then kills all of Wismerhill's friends one by one before battling his erstwhile student to the death. As he's dying at Wismerhill's hands, Haazheel uses his dark magic to curse the entire world by ensuring that the moon will leave its orbit and cause The End of the World as We Know It.
Evil Is Cool: Make no mistakes about it, Haazheel Thorn is pure evil, but there's something to be said for an archmage who had enough will of mind to build an entire religion around himself, effortlessly slaps around giant demons, has a succubi harem, can resurrect people from the dead, transforms into either a hulking behemoth or a four-armed Kaiju monster, and lives in a fantasy moonbase.
Haazheel Thorn and Wismerhill are the only two people who are apparently unaffected by succubi. This is because both of them are half-demons.
Greldinald's ability to unite the orc clans through violence is because he was Raised by Orcs.
Growing the Beard: This was the first major comic series for both Froideval and Olivier Ledroit, and early on it shows. Each successive volume shows incremental improvement, but come volume 4 everything becomes markedly better.
Mary Suetopia: Wis tries to run one of these, helped by an extremely elaborate religion that also serves as information relays. The fact that his "Complaints Department" is Ghorgor, a huge axe and a huger grin helps a bit.
