An imperial guard legion was once present- the Tanaroth 1st, but this was later disbanded due to a lack of new recruits after a particularly crippling campaign against eldar exodites. The planet lived on in peace for a good long time, never threatened by other life forms, or corruption in the guise of chaos or genestealers. This was to soon end, however, as the harbringers of destruction came in the form of orks. Lots of orks.

They hit the world like a fist punching a paper bag, orbital defences offering little resistance and adeptus arbites and personal armies giving no realistic possibility of a counter-attack, or even a half-hearted defence. The troops were crushed by the green onslaught. The man at the head of this defence was Lord Feralin Romuli, imperial ordained ruler of the planet. He died fighting, killed by Ogryns lured into fighting for the forces of the greenskins. His son, however, lived on..

And what of Tanaroth now? It is a place aflame, ignored by the imperium, riven with bands of orks, overrun by madmen- chaos worshippers, cultists venerating the evils of genestealers, redemptionists seeking to purge all for the glory of the Emperor, and normal civilians who could not handle the depravity and horror there.

These individuals, although cursed by the Emperor, for those of holy spirit will survive, and all others should die as heretics, may have some reason to lose their sanity. Eldar pirates roam the streets seeking victims with which to torture, strange life forms such as Tau and Kroot wander the ruins, and vigilante humans steal weapons from age-old factories, waging war on other gangs of humans.

However, some things have remained from the time before the orks. Apherus Romuli, great-great grandson of the brave and noble Lord Feralin Romuli lives. He lives in ruins, in caverns, in makeshift villages in less deviant-infested areas. He wages war against these deviants, his friends, advisors and strategists acting as trainers and sergeants to right-minded civilians, and keeping alive the order of adeptus arbites, the elite police force of the imperium. These warriors perpetrate guerrilla warfare against the heretics, attacking bases and meeting places of powerful opposition, be they human or alien.

But then this changed. For one day the imperium ended their bid to forsake Tanaroth. An inquisitor arrived. His name was Kryptman. Romuli and others rejoiced, for they were to be saved from the evils of this place by a merciful imperium! An astonishing thing happened: the aliens and heretics began to flee the cities and settlements of Tanaroth, fighting among each other as they went. This was exactly what the peoples of Tanaroth had been hoping for! A gracious and legendary inquisitor arrives, and the horrors go away! The inquisitor did not speak with officials, hiding out away from others, but this was not too much of a problem, as he had already done the planet a mighty good, and they were thankful for it.
