While Halvard and his people soak their land in magic they all but forgot that all magic no matter how small and mundane has a price. Every cleaning, washing and lighting spell left a mark. The bigger magic like rituals evoked gods that previously is not cast their eyes upon this realm before. The saw a ream not connected by Yggdrasil before the realm's gods where weak compared to them, a fire god that burned his followers for power, a knock off Jötunn who had gathered a Draugr army and a variety of smaller gods that where not even worth mentioning. Then Ratatoskr had found who had evoked their name a seiðr had somehow found their way here and began to spread their magic all over the realm.
So the Gods began to watch and send scouts to the Realm the found to be named Planetos a rather uncreative name, but the scouts had found that magic had been in waning most of the world and their new seiðr had started a chain reaction to strengthen it. The seiðr even brought back spirts much to the delight of Jörð as the were her first creations, she even went so far as to pick the first druid of this realm a young girl named Eldrid who Jörð began to visit the dreams of to teach her the way of nature and earth. Eldrid much to the goddess surprise was not scared of her but thought the goddess to be her grandma to which the goddess did not correct and told her stories of the Æsir and the Vanir, while teaching her the basics of nature magic.
Odin then out a plan in place as the worship of them had began to weaken in their realm, he had his wife agreed that they shall replace these old gods, soon the Priest of the old gods began to have dreams of The Old Gods and their names and now they were to spread their names and deeds to all the North. Thus the Norse Gods gained a hold upon Planetos soon all the noble houses of the North were told that the Old Gods had given their names and their stories back to the North. This was met with great skepticism from the nobles but as more and more came forward they were forced to agree. Then the gods began choosing new paladins and clerics to guide their new worshipers.
Soon the gods chosen were picked; some in the midst of a Iron born raids, another a child abandoned to the elements taken in by nature, a son of a blacksmith was given divine guidance, a child with greyscale healed and may more were picked all worshipers of the Named Old Gods. Though they may be young they have a great destiny.
With spirts released into the world another plane had come into being. This realms Spirt world, soon spreading from the North new spirts entered the world; beyond the wall wildings began to find ice spirts destroying Draugrs, in the North's old forests nature spirts began saving kids, Vale Earth elementals began taking over abandoned mines, Riverlands Water elementals drowning those you travel to close, Westerlands Air elementals threw men off their mountains , Stormlands lighting elementals, Reach tricksters spirits began taking hold in homes, and Dorne Sand elementals. But the list goes on as more and more spirts are making their way to Planetos and unknown to the players of Game of Thrones more player have entered and they play by very different rules.
