Lustlord

Story
Strictly speaking Lustlord is not his name, but just his title. As the oldest among the Incubus Kings, it seems that the responsibility of hosting The Gathering befalls on him. A holder of a major soul fragment, but he seems like a bit of a doormat. Definitely not the succubus god of the same name, though he would obviously like to be that. During the first meeting, outside of the Abandoned Fortress, Yarra estimates that he's about as powerful as the Incubus King.

As it was foreseeable in someone as full of himself as this one, he barely reacts to the presence of Yarra and the others as they are people so below of him to even acknowledge their existence.

His country (or domain) is called Rodak. As a ruler, he is not the worst of the lot but that doesn't mean that he is a caring person. The group has little opportunity to learn much more about him directly, but at least they have time to make some connections with some of his subjects.

He has a tremendous ego, as might be expected from someone who literally describes himself as a god, but it is surprisingly fragile. Notably, being reminded that he was once the youngest Incubus King in a gathering of long-dead elders throws him into a rage.

The origin of his huge wealth in a isolated (and desolate) domain is unknown but it's a matter of interest by others, especially for the party-crasher queen Fheliel, ruler of Ghenalon.

He seems to be particularly interested in impressing his peers with his wealth and power. He is not above reminding the others that he is the oldest among them. He is also petty enough to reinforce his prominence with trivial mind games, such as the size and ornaments of his visitor's suites.

His subjects are in general very good hosts, very well mannered and extraordinarily kind. They don't seem to be treated roughly or at least you see no evidence of that kind of behavior.

At the end of the Third Arclent War, he tries to steal the Incubus King's shard from Simon, but is stopped from doing so by the Empress.

During the Erosian crisis, he approaches the Doom King and proposes an alliance against Estaven. In his proposal, he would refrain from interfering with the war, and, as compensation, would receive half of Estaven's shard and the assistance from the Doom King during an eventual war with the Orgasmic Empire. Esthera notes that this is a quite one-sided alliance (the Doom King does all the works but only gets half of the prize). She also mentions how the Lustlord seems obsessed with her in particular.

During the following war between the Doom King and the Fucklord, he waits until the latter is injured and tries to kill him to steal his shard, granting him an easy win on Thenours. His army invades Ghenalon at the same time. However, this doesn't work out as planned. Estaven manages to flee while the Lustlord ends up in a fight against both Esthera and Ginasta. The invasion of Ghenalon fails too, and he's forced to retreat.

Sometime after that Great Thenoursan War, he captures Ginasta and begins to uncreatively torture her in an attempt to break her will or make her serve his purposes. He loses her during an invasion of several other Tower walkers, leading him to propose a Second Gathering to regulate the use of the Tower and identify new Incubus Kings who attend. At this Gathering he and Esthera antagonize each other until he declares that her defenses cannot keep the Gathering safe from imminent attack by Chosen, and demands her submission. Instead, despite revealing unexpected personal power, he is defeated by a coalition of Esthera, Xestris, and Simon's group, and Simon claims his Incubus shard.

Trivia

 * His character art was made by a Japanese artist who posted it on the Closet blog. You can find it here.
 * Said artist called the character "Dio". This name is still used in the game files for the Lustlord's portrait.
