Magni
I am Magni. I am the son of ice and frost; I am the Winter and the Snow and the North Wind. I am the first and foremost of my kind and kin the hrímþursar, the rime-thurs in the script of Man; and in turn we are among the greatest of all the kinds of giants with only the jötnar of Muspelheim being stronger but their kind are long defeated for they were broken in a great war against the Æsir and have mostly left the lands of mortals to nurse their hurts and plot with malice against the new order of Æsir who rose from the ashes and made all the great hurts of the jötnar of Muspelheim in vain, for they had sort to slay the Æsir and the Vanir, the greatest foes of the jötnar, for all time and while the few Æsir who survived are weak the jötnar of Muspelheim are weaker still. Thus it is the time of the hrímþursar, the Æsir's power is broken and the Vanir that still live and escaped the great battle can be broken too by the might of the hrímþursar.
I once lived in Asgard and the halls of the Æsir and I fought my kind and kin at my father, Thor's side and I was regarded as one of their number. I survived the great battle and I fled from the land of Asgard at great haste, for I knew that the Æsir were weak and I could overthrow them. I fled to the lands of the jötnar, Jötunheim and Niflheim (Niefelheim spelt properly), and there I was perceived as one of the Sons of Nifl (Niefel spelt properly), of mist and snow and cold and winter, and the jötnar began to see me as greater than their own chiefs, whom they abandoned, and worshipped me as a god. Their chiefs were not pleased at the desertion of their followers and gathered their remaining strength into one mighty host led by the greatest of their number Bergfinnr, son of Thrym. My followers were greater in number but their skill at arms was far less and Berffinnr had great practitioners of seid (one of the forms of magic in Norse mythology), who knew many galdrar (spells) that might turn the battle in the favour of Bergfinnr. Yet I was greater than even his greatest sorcerers and I broke them for my knowledge was far greater and I had learned the arts of seid from Freyja herself and no mortal man or jötnar could oppose me in that art lest they too ranked among the Æsir or Vanir in the elder days. Yet Bregfinnr did not fear for his warriors were of greater skill and valour and the centre of my army was broken before their might and all looked bleak. Once more I called upon the seid and the army of Bredfinnr found their blades blunted and their armour grew soft as clay and clung to their bodies and prevented them from moving with ease. They were cut down by the remaining warriors of my command. Still Bregfinnr and his guard persisted and marched on towards my men. I ordered them to retreat and marched forth to meet my enemy. Bregfinnr and his guard, seeing that my followers ran, laughed and cried out:
"Look how the men of the 'god' run rather than face their doom. For they know that their 'god' is nothing but a trickster who has met his match. Trickster turn and run with your men and we might spare you death. You could be our thrall and work your seid for our gain. Why would a 'god' use such unmanly arts anyway for all know that the practitioners of seid tire and grow weak after using their arts. Run or face your end."
I replied:
"You face one of the Æsir, the son of Thor the Bear, no less this day. You will fall as the price for your pride."
And with those words spoken I charged the ranks of the chiefs of the jötnar and they scattered or fell were they stood, such was the might of my charge and my skill with my axe. Bregfinnr berated his men crying out:
"He lies! He is no son of Thor for the son of Thor must be the wielders of his mighty hammer, Mjöllnir, as Thor is dead. Where is the hammer?"
"I am not the only son of Thor. My brother keeps Mjöllnir," was my reply and, having spoken my reply, I smote the helm of Bregfinnr with my axe and cleaved it into two halves. Then I smote his face with my fist and I struck him dead and thus Magni, son of Thor, came to be lord of the jötnar.
OOC notes: The names are correct for Norse mythology and the great battle is of course the battle of Ragnarök were the Æsir and the jötnar and various other creatures fought with each other. Magni and his brother Modi both survive Ragnarök and later, along with a few other survivors, found the next group of Æsir, whom we know nothing of. Of course not all the the events are correct and Magni never did become lord of the jötnar. Wikipedia is your friend if you wish to find out more about Norse mythology quickly and easily.
