Daemonettes

Daemonettes are Slaanesh's most numerous warriors/courtesans.

According to their history, Daemonettes is like a seducer, temptress and a warrior combined. These hideous creatures has, as you can see, mutated parts of their body, most likely half male, half female and a set of clawed feet. 

As the messengers of Slaanesh, it's the Daemonettes that's called upon when humans or other alien races tries to communicate with the Dark Prince.

Appearance 

When people sees the Daemonettes, they see the ultimate aspect of beuty and seductivness although that's hardly the truth. As you can see on the left picture, they're extremely hideous and repulsive to the naked eye. they have a crab-like talon, one boob and a face that only a mother can love.

Fuegan - The Burning  Lance

Of course we all know Fuegan on one Aspect. He's the Phoenix Lord and founder of the Fire Dragon Aspect Shrine.

Like all the Phoenix Lords, Fuegan was trained under he vigilant eyes of Asurmen in the arts of combat. All the Phoenix Lords developed their own unique style of combat, where  Fuegan's was the utter destruction of their target to ensure that they stay dead and bring the galaxy a step closer to peace and harmony.

Prophecy and History.

When you mention Fuegan in the Eldar Circles, they'll most likely depict him as the one who holds the cosmic serpents of entropy and wisdom in both of his hands.

It's like he's depicted as a greater demigod as the others, when you hear him set a whole world ablaze with but a mere footstep, his eyes bring about the fiery destruction of his enemies and there's nothing but smoke around him, when people, human or not, earns his wrath. He's also the one who's fully obsessed at a higher rate than all the other Phoenix Lords combined. He's fully synonymous with his Path of War and he's quick on the trigger when an enemy shows. Nothing will stand in his way

Such is the depiction of Fuegan's History. During the end of his training and the building of his shrine, he disappeared and no one knew where he went. People were worried but suddently, during an important battle that took place on the planet Haranshemash "The World Of Blood And Tears", he appeared with a group of Fire Dragons, helping the Eldar by fighting side by side with them.

Next time he was sighted, was on Medusa V. There he led another group of Fire Dragons and assaulted an Imperial Fuel Deposit. I have no idea why, but apparently, it was important to some kind of prophecy.

Maugan-Ra

Like a few other Eldar's, Maugan-Ra is a Phoenix Lord, an immortal Eldar entity who can never truly be killed. whenever the current form of a Phoenix Lord dies, they'll be reborn as soon as the best candidate puts on the Armor. Maugan-Ra, together with 7 others, studied under Asurmen "The  Hand Of Asuryan".

Each Phoenix Lord created their own form of Warrior Aspects.

Maugan-Ra created the Dark Reaper Aspect Shrines. Dark Reapers consists of long versions of the Shuriken Cannons mixed with an Eldar Power Weapon, so they can be devastating in both melee and ranged units

History

Maugan-Ra studied together with the 6-7 other Phoenix Lords in the Path of War. Maugan-Ra was, at that point, the only Eldar to escape from the Craftworld called Altansar. Altansar was trapped in the Warp a small 500 years after the Fall of the Eldar. Maugan-Ra were devastated of course, but he couldn't do anything about it when Altansar was sucked into the Warp and was seemingly lost forever... Or so they thought..

During the 13th Black Crusade, when the Warp expanded so much during the breach, or rather, The Rift expanded. That's where Maugan-Ra saw his chance to go look for them again. He got to a lost Crone World of the Eldar called Belial IV where they thought against the forces of Chaos. In the end, Maugan-Ra were nearly devastated, but Altansar appeared before the climax and pledged their aid to Maugan-Ra, Luckily, they survived ten thousand years within the Warp, although at great suspicion from the other Craftworlds, because the Eldar of Altansar refuse to remove their helmets, even under duress.

Luther the "Arch-Betrayer".

Luther, the man who found Lion El'Jonson, were one of the greatest, if not the greatest man, on Caliban.

Luther were an acclaimed Knight of the Order of Knights, an estemmed order of which Jonson ended up as Supreme Grand Master by killing a Great Beast.

Luther was unfortunately too old to become a true Astartes when the Emperor came so he was genetically enchanted to be nearly as powerful as a regular Astartes. Unfortunately, this made a deep scar within Luther, because he became jealous of those he tutored. they became Astartes, he didn't.

Luther was born on Caliban, came with the Lion and then back to Caliban again. When Luther arrived on Caliban again, he became enraged and even more jealous when he hears the news about the Lion's victories across the galaxy, which made Luther turn Heretic.

When the Lion returned to Caliban, Luther had swayed nearly all the stationed Space Marines to his side. 

The Lion, enraged at his surrogate father's betrayal, launched a tactical bombardment on the planet which cracked the entire planet and made everything explode, except The Rock which is protected by potent force shields to prevent damage. 

Luther and the Lion thought for a bit but as Luther dealt a psychical blow to the Lion's mind, a veil was lifted from his eyes and Luther repented his sins by refusal. Refusal to fight his son and everything else.

The Ruinous Powers, enfuriated at Luther's turn, unleashed a massive warp storm and ripped him of his mind, making him mentally unstable at best.

Now, Luther resides deep within the deepest chambers of The Rock in a stasis cell. Every Supreme Grand Master of the Dark Angelsk Legion has visited him atleast once to see if they can deprive some prophetic truths from him. Some have, but other times its just rambling madness from an unstable person. He whispers that the Lion will return and repent him for his sins and make him one of the Dark Angels again. Something that's yet to be seen, but maybe it will be.

Lion El'Jonson

The Lion was, aswell with all other Primarchs, made on Terra, but sucked into the Warp by the Chaos Gods.

Lion El'Jonson crashed on the Death World of Caliban. He was found and raised by Luther, The Lion's second in command before the Horus Heresy. Lion was quickly persuaded to join the Order of Knights, which he did. It didn't take him very long to become the Supreme Grand Master of the Order, having eradicated one or more of the Death World's Great Beasts.

Jonson was found by one of the forward scouts of, ironically enough, the Dark Angels who told the Emperor that he found one of the Primarchs. 

The Emperor arrived during a Great Hunt, the final one to be precise, and quickly swore his fealty to the Emperor, thus renaming the I Legion to The Dark Angels. 

Lion El'Jonson won many victories across the galaxy in the time of the Great Crusade, but Luther and a handful of the Dark Angels were sent back to Caliban because of a mistake that could've killed them all. A nuclear bomb were smuggled up in a shuttle next to the Flagship of the  Dark Angels during a treaty/bargaining for a group of people to join the Imperium.

Luther was then corrupted by Chaos due to jealousy and a little bit of hatred towards the Lion. 

when Lion El'Jonson returned to Caliban, Luther ordered the orbital defenses to fire upon the Lion, thus a little war started. The Lion succeded in finding Luther and battle him, but was mortally wounded before a massive warpstorm hit Caliban and thus shattering all except the Order's Monastery, also called The Rock. Now, Luther is encaged within a stasis cell deep within The Rock, a secret known only to the Supreme Grand Masters of the Legion.

Ahriman.

Ahriman is one of the greatest sorcerers still alive in this universe. He's the one who's responsible for the creation of the Rubric Marines by conducting the Rubric of Ahriman to save them from the rapid mutations that had sent almost the entire Legion to its knees. Of course, the Legionnaires were saved, but without magic in their blood, they were transformed into shells, a living armor. The sorcerers, however, were made even stronger and more powerful. Ahrimans own powers were augmented so much that he became the strongest sorcerer next to Magnus the Red, the Primarch of the Thousand Sons.

Because he conducted the Rubric, Magnus banished him from the Legion, making him a wanderer across the galaxy where he gathers further knowledge to reveal some of the greatest mysteries ever - To see if he can finally grasp the nature of Tzeentch himself, something that's impossible because  Tzeentch's nature is unreliable and random at best.
