House Adana has always inhabited the lands they currently live upon. For as long as their histories can remember, they were there. They have not always been titled "Adana", however. The first three generations of their family - that their histories can recall, as there could very well be previous generations that were forgotten about - shared the name "Nilashka." In fact, it was one of these Nilashkas that spurred the change of name.
The Adana family and its peoples have always been very warlike. They have fought countless times over the generations in defense of their lands, and sometimes even in the name of conquest. It was one such conquest that resulted in the current name of the House. Princess Adana Nilashka, daughter of King Drulus, was at the time the commanding general of all of their armies. She was ruthless, brutal and effective. She is in fact the very reason the Adana family possesses as much land as they do. All the lands she took; all the castles and towns she stormed, created a legacy that none would soon forget, and for generations the Adana family and all their subjects have been fighting for that legacy; protecting it.
There is one story in particular that drives on the Adana family and the soldiers that fight for them, and that is the tale known as Adana's Fall. During her life, war with the kingdom from the sunny southern parts of the lands (Dorne) never ceased. By the time she took control of their armies, they had been pushed almost all the way back to the Crescent Woods. The only lands they possessed were the Crescent Woods themselves, their capital located within the woods, and the castle of Dunfir (Summer Hall.) This castle, besieged by the armies of the south, is where Adana resided. After the siege the castle was renamed Ironwall in honour of the defeat of the southern armies.
The war from here still did not go easily for the Kingdom of the Middlelands. No, it was a drawnout, bloody, grueling conflict. After months and months of fighting, Adana and her armies managed to reclaim - and expand - every bit of their land bar one: The Dam, situated just north of the pass in to the lands of the south, called such for the role it played early in the war in holding back the southern armies long enough for the rest of the Nalishka forces to get assembled. By this point in the war, The Dam was the last foothold of the southern armies and its retaking would signal the vanquishing of them from lands that the Nalishkas considered their own.
The battle was possibly the fiercest any of the soldiers of either side had ever seen. At one point, the Nalishkas had almost taken the city; it was so close that all of them could taste it. But it was at this point that everything went wrong. An archer on a roof pierced Adana's shoulder with an arrow, which opened her up for the two she was fighting. In front of all of her soldiers and all of the enemy soldiers, she was cut down, her battleaxe Moon's Light falling to the ground. The morale of the southern defenders surged at this point, crushing the remnants of the shreds that had become of the morale of the Nalishka army upon seeing their leader fall. With her death, Adana's army was broken and the southerners won the day.
The Battle of The Dam marked the end of the Nalishkas' war with the southerners. Both sides had depleted their resources to such a point that neither could afford to supply an attacking army. But that did not stop the hatred. Adana's six year old son, Valrus, grew up knowing that the southerners were the reason he had no mother. Ten years after her death, at the age of sixteen, Valrus went to war. He rallied the armies of the Middlelands, conquering their fear of the castle they had come to call Adana's Fall and replacing it with hatred, anger and a lust for vengeance. The armies of Valrus Nalishka marched south, laying siege to Adana's Fall. They shattered the walls, leaving so many holes in them it would take months to repair them all. They burned every single building in the place, leaving nothing more than ashes in their wake. And the Duke of The Dam? The thief of Adana's sacred weapon? He was not killed. Not straight away. He was captured, tormented, and tortured until he begged for death. And then he was tortured some more.
This act, however, sparked war once more, and Valrus Nalishka spent his life fighting the southerners. Early on in this war he renamed himself Valrus Adana, both in memory of a mother he could scarcely remember and in order to strike fear in to the hearts of his enemies, for they knew that name. They knew of Adana, the Nalishkan Butcher; the very woman who had shattered every army they sent against her; who had executed every soldier that surrendered. To the men of the Middlelands, she was a hero. To those of the south, she was an evil woman, hellbent on destruction and death. But whether she was seen as a hero or as a menace, one thing remains true: her name has lived on through the generations, carried by every one of her descendants, and they have fought for the land she carved out for them, laying down their lives in defense of it, for it is more than simple land to them. It is the land of their people; of their ancestors. The blood of their forebears was spilled in magnitudes never seen since, and as such it is sacred. The Old Gods protect them and watch over them, but it is they who must protect and watch over their lands and their people.
