Well I was too lazy to make apps for most of them even in the previous OOC. Though I did make a reference thing for most of the Lords of Hell.
For that, look up Diablo, Mephisto, Baal, and amybe Azmodan.

Maybe I should list the other lords here, as for reference, then i'll probably go to bed.
Mephisto: Lord of Hatred
One of the oldest of the Evils, and the most intelligent. The closest that demonkind has to a "Leader". He is the most intensely evil of all of the evils, so much so, in fact, that his influence can bring the dead back to life with a hatred that can't be quenched with a second death. He is highly intelligent, and highly skilled with every form of magic, and his armies reflect the pure hatred that he has fro everything.
Diablo: Lord of Terror
The yougest of the Evils, but known at the most powerful, with the ability to instill fear into the hearts of people with the simple mentioning of his name. He can envoke fear in any opponent he may face, and due to him being the aspect of fear, he cannot feel fear. Physically, he is the strongest demon in existence, being able to level mountains with a single stomp, though he prefers to work behind the scenes, manipulating things to his will, and corrupting people to his bidding. He is also known to be in control of very powerful fire magic, and so does his own armies.
Baal, Lord of Destruction
Baal is one of the most destructive forces any world has ever seen. With a constant lust for battle and chaos, for being able to destory anything that comes in his way, and for his armies packing enough brute strength to level heavily armed fortresses with a single squad, Baal is a force to be reckoned with. In truth, not much really is known about Baal, due to his limited appearances in a single expansion for Diablo 2.
Duriel, Lord of Pain
Duriel presides over the Realm of Pain, the lowest level of the Burning Hells, where the worst of the worst go. To be simple, it is a giant torture chamber, where those torture suffer the worst forms of torture imaginable, and unimaginable. He controls pain, and can render it onto other people, though no actual injury was inflicted. His minions are extremely durable, even those without armor, and he is known to take delight in torturing others.
Azmodan, Lord of Sin
Azmodan is known for having the most powerful army known in the Burning Hells, both in size, but in strength. His presding over Sin gives him control over the embodiments of those sins, such as Ghom, lord of Gluttony, or Cydaea, Mistress of Lust, along with many others. He himself is physically and magically powerful, being able to summon hordes of demons, pools of molten lava, and many other things.
