Origins
The Forming
After the Lion's speech, a group of Dark Angels broke away to the Cadian Gate, planning to wait there for the Lion to return and to follow Him into the Eye of Terror. The journey went without problems, and they arived in fair time at the Cadian Gate and waited for the Lion to join them.

Pre-Heresy Dark Angel.
They waited for several months for the Lion's return, and little did they know of what happened at Caliban. Grand Master Mordekai decided to send a message to Caliban, asking what happened to the Lion.
After a few weeks he recieved word of what had happened. And, in his anger, ordered his fleet to plunge into the Eye of Terror, to exact vengeance upon their fallen brethren.
The Eye of Terror
As the name suggests, the Eye of Terror is a place that can drive the most hardened man insane, and yet they entered. As they appeared out of the warp, Grand Master Mordekai adressed the fleet; he told of what happened at Caliban and that vengeance was theirs. That it was their holy duty to make their fallen brothers repent, or to kill them if they didn't.
While they were in the Eye of Terror, the other Chapters captured the Cadian Gate and constructed defences in its place. Making sure that noone could leave or enter the Eye of Terror without them knowing.
This effectively lock both the Chaos Chapters as well as Grand Master Mondekai's fleet inside the Eye of Terror.
The Change
They fought many battles in the Eye of Terror on various daemonworlds. It happened on an Slaaneshi daemonworld; they were struck by the vile magicks of Slaaneshi psykers, changing their very essence and mutating their geneseed. Fearing the worst, they withdrew from the planet to see what had happened to them. Their Apothecaries examined their geneseed and noticed only one small change, a change too horrible to reveal to the Imperium, or even to their own Legion Brothers outside the Eye of Terror.
In reflection of the change, they changed their Chapter structure, as well as their names. Grand Master Mordekai announced this to the Chapter, as well as his namechange; changing his name into Grand Mistress Onisuzume. They would be Battle Brothers no more, instead they would refer to each other as Battle Sisters.
The Escape
After their restructuring, they decreed that they would leave the Eye of Terror. Making their way to the Cadian Gate, they noticed that they would appear to be an Chaos Invasion to the defenders on Cadia, thus they decided to search for an other way to leave.
Their chance came with the Gothic War, which opened a second path into the Eye of Terror which the legions of Chaos used to launch one of their Black Crusades. Grand Mistress Onisuzume ordered her fleet to follow their Chaos brethren out, and into the Gothic sector.
The Gothic War
With their main priority being their journey to Caliban and rejoin their Legion, they hid for the better part of the Gothic War. Only fighting to preserve their hidden existance, and leaving barely any impact on the Gothic War at all.
Homecoming
After the Gothic War, they set course for Caliban; a journey that took only a few weeks. When they dropped out of the warp, they noticed to their horror that their once beautiful homeworld was no more. Instead of finding a large planet with lush jungles of a verdant green and wide oceans of azure, they found clouds of fine dust, flecked by the occational small astroid.
Their homecomming hadn't gone unnoticed, however, and soon they were hailed by an Dark Angels strike cruiser. Paniced, Grand Mistress Onisuzume donned her helmet in the hope that it would warp her voice. The captain of the strike cruiser, however, was surprised to find a fleet of Space Marines wearing ancient power armour and bearing the original Dark Angels markings. Thinking them to be fallen, he issued an order to the rest of the Chapter.
The Confrontation
As the rest of the Chapter dropping out of the warp, Grand Mistress Onisuzume hailed the flagship. Greeting the Supreme Grand Master and telling him of their crusade. The librarians examined their archives and noticed that a number of ships had been lost in the warp a few weeks after Caliban was destroyed, ships bearing the same names and markings as the ones they had encountered. Convinced that they spoke true, the Inner Circle called a meeting to decide on the fate of the returned Dark Angels.
Their Fate
With the entire fleet knowing of the fall of the Lion, as well as the Betrayal of Luthor, it was decided that they were to be inducted into the Deathwing. They were to remain unknown to the Imperium so they could focus on hunting the Fallen, and nothing else. It was decided that they were to retain their black armour, while their Chapter Badge was to be changed with a sword broken painted red. Represeting their status as members of the Deathwing, and reminding them of their duty to hunt the Fallen.

Angel of Devastation.
Homeworld
Walkura is a system situated north-east of the Gates of Varl, the very edges of Imperial Space. Walkura V, the homeworld of the Angels of Destruction, is a large planet orbited by three moons, which maintain a constant sealevel with little to no ebb or flood. The planet is covered by large mountain ranges and huge forests, as well as a couple of large lakes which are filled with fish. The forests are teeming with wildlife ranging from various small rodents to large and docile cow-like creatures the size of a small house. Tall and foreboding, the mountains are thousands of feet high and are scarecly populated by the most dangerous beasts of the system, which occationally prowl through the forests in search of prey.

Walkura V.
The local population has regressed into a medieval state ruled over by a matriarchy. They live in small to medium sized communities which are protected by wooden stockades. The land surrounding these small forts has been cleared and is used for agriculture. Becouse roughly 80% of the population is female, it isn't unusual for women to do work that would normall be done by men on other worlds.
Located in a remote area of the planet is the Chapter's Fortress Monestary. The huge building is easily the size of a small city, if not larger, and houses almost the entire Chapter. It's gothic architecture stretches hundreds of feet into the sky, the main tower is so high that it can be seen
from miles away. Most of the fortress' halls are decorated with statues of angels, many of which also serve as supporting pillars. Many walls are adorned with murals depicting the Chapter's history. The lush forests surrounding the fortress are excellent for training new recruits, or for keeping the Sisters battle ready by means of simulated battles.
Because of the planet's three moons, the planet itself is lacking any form of planetary defences, which have been build upon the moons instead. The moons also serve as the Chapter's production centres, as well as the fleet station.
The moons are also home to the Chapter's Librarium. The Librarians are deemed to dangerous to keep on the planet.
Techmarines live most of their lives on the moons, where they work, live, sleep, eat and train new recruits in the ways of the machine cult.
The Apothecarion is located in a wing of the main fortress on the planet, where they train new apohtecaries, as well as maintain the Chapter's Geneseed.
Combat Doctrine
Though they recieved a copy of the holy Codex Astartes from their Primoginator Chapter, they still follow a mainly Legion-style force. With five or ten strong squads to maximize firepower compared to the menpower used. The Paladins are always fielded in five-strong squads, while the Knights are fielded as either three strong or six strong squads. Optionally, the Knights are fielded with either an attack bike, an land speeder, or both, or as an squad mounted entirely in land speeders.
Organisation
The Chapter follows an non-codex organisation. Squads are drawn from three different reserve companies, which are then put into a company of varying size, depending on the situation and campaign. The first company is always fielded in Tactical Dreadnought Armour and are known as Paladins; the Angels of Destruction's equalevent of the Dark Angels' Deathwing. While the second company is similiar to the Ravenwing. Like all Unforgiven Chapters, the Angels of Destruction have their own Inner Circle. The Supreme Grand Master is the highest ranking member of the Inner Circle, and all Grand Masters and Masters are members to it.
Beliefs
Since over half of the Chapter remembers the time that the Emperor walked among them, they acknowledge Him as a mighty warrior, a great leader, and as father to their Primarch, Lion El'Johnson, though they refuse to accept His divinity. Their Chaplains, however, do preach to the people of Walkura V of the Emperor's divinity, and that they are His Angels.
Geneseed
Their geneseed, though mutated by chaos, is still one of the purest, and has lost none of it's functions. The only differance with the Dark Angels' geneseed is the incompatibility with male genes. And as such, they have to recruit from the planet's female population. Many of who are stronger, tougher, and more capable then the men.

Chapter Standard.
Battlecry
Since tey are still Dark Angels in mentality, they still use the same battlecry as they said ten thousand years ago.
"Repent! For tomorrow you die!"
