"The Horus Heresy

Thousand Sons Legion were never traitors and did try to warn the Emperor of man about horus and other traitors, At this time the Emperor could not see his son horus back-stabbing him and so sent the Leman Russ and his Space Wolves, the Adeptus Custodes and the Sisters of Silence to take Primarch Magnus the Red and bring him back to earth.

Before committing his forces to the attack, Leman Russ, commander of the invading Imperial fleet, attempted to communicate with his brother, Magnus. Believing that Kasper Ansbach Hawser was a Hidden One of the Thousand Sons, Russ attempted to speak to Magnus through him, declaring his fleet's approach and making a request to send away the civilians and surrender. As Hawser was not a Hidden One, but actually a pawn of Chaos designed to appear as one, the message was never received. Leman Russ ordered the attack

With no fleet in orbit, Prospero had to rely on her orbital defence batteries as first-line protection. These stations lasted but mere moments, with torpedo-spreads aimed at them released from the Imperial vessels. Survivors of these torpedo attacks were bracketed and then obliterated by long-range gunfire as the fleets closed in.

board which they found Mahavastu Kallimakus, the Scribe of Magnus, a valuable capture.[2b] Taking up orbit themselves, the Space Wolves' vessels commenced saturation orbital strikes upon the entire planet. Magma Bombs, directed energy-weapons, mass-drivers and even ballistic cannons were unleashed upon the surface of Prospero, in an assault that literally changed the surface of the world forever: mountains were levelled, valleys filled with their rubble; the seas were boiled away, flashed into steam; the very bedrock of Prospero was pounded and heated into new shapes, like metal upon the anvil; boiling hot winds swept across the world, bringing with them the smell of heated metals and oils.

This bombardment was so sudden and so strong that moments after it began, only one population centre still survived on Prospero: a standing unit of Thousand Sons from the Raptora Cult kept a telekinetic shield generated over the city of Tizca. This shield, as hard and impenetrable as those generating it could mentally conceive, proved completely proof against the fearsome orbital bombardment directed at Tizca, even though sympathetic damage to the kine-shield killed several members of the cult maintaining the shield.

The Space Wolves continued the bombardment of Tizca for some time, perhaps hoping to overload the mysterious shield preventing them from obliterating the city. The time this tactic created allowed the commanders of the Thousand Sons to confer and learn what was happening from Magnus the Red himself. Magnus implored his Legion to give up any notion of defence and accept their deaths with honour. Perceiving the truth of the matter, that Magnus had seriously transgressed against the Emperor's decree and behaved in such a way that the Imperial forces considered the Thousand Sons to be compromised and traitors, Chief Librarian Ahzek Ahriman realised that the legion was damned if they did and damned if they didn't. He therefore resolved to ignore Magnus's wish (in a minor reflection of Magnus's own attitude towards the Emperor's wishes) and lead the Thousand Sons in defence of Tizca and the lives of all within. The senior captains of the legion assented to his command; the Thousand Sons did not intend to perish without a fight.

Leman Russ, Primarch of the Space Wolves led his legion to landfall, The 15th Prosperine Assault Infantry took up positions in a line between the Pyrae Pyramid and the Skelmis Tholus. Their commander, Captain Sokhem Vithara, made the Kretis Gallery, the oldest museum and art gallery on Prospero, his headquarters. The Prospero Assault Pioneers dug themselves out of their collapsed barracks and prepared to sell their lives dearly, Leman Russ and the Space Wolves hit Aphea's line next and overran it within minutes. Tizca was burning.

It was at this point that the Thousand Sons marines made their presence known, their captains acting in accordance with their hastily-made defence plans. Ahriman led the Scarab Occult in to reinforce the 15th Assault Infantry. Although the Spireguard unit had some success with using the narrow streets of Tizca to their advantage, the were but mortal soldiery, and the Scarab Occult arrived just after the Wolves managed to break through. As Ahriman formed up his gun-line in front of the charging Wolves, he peered down the length of his bolter and found the precognitive thread that would guide his shot into detonating the helm of one of the Space Wolves. The significance of this moment made him hesitate, with the result that the charging Space Wolves opened fire first, smashing several of the Sekhmet to the ground. This action broke Ahriman's hesitation, and he pulled the trigger, killing his first Space Wolf mere moments before the rest of his elite company opened fire, knocking the Space Wolves back. The stunned Wolves were then struck by the various psychic powers employed by non-Corvidae members of the 1st Fellowship, with the survivors either variously being telekinetically mauled to death or burned alive. Not a single Space Wolf from this attack lived, and with clashes like this repeated everywhere the Space Wolves met the Thousand Sons, the first defensive line was formed.

Cant put the rest of it in as their is just so much to sum it up the Thousand Sons Legion and the space wolves would fight almost to the death, Magnus would fight Leman, Leman would win and Magnus would run away taking with him what was left of the Thousand Sons Legion. But this was all a trap set up by horus.....

I did not make this and if the owner wants me to take it down all they need todo is ask.
