Icepeak was a kingdom made up entirely of ice, located somewhere in the north, which was ruled by the ruthless ice tyrant Lord Nekron and his mother, Queen Juliana.
Before the war[]
At the beginning of Fire and Ice, the female narrator states that Nekron used his powers to take control of Icepeak, implying that he did not form the kingdom and was not the only ruler.
War[]
Once Nekron came to power in Icepeak, he became more power-hungry and set out to conquer all of the world. Using his supernatural powers, Nekron was able to physically move and expand Icepeak. He pushed through Larn's village and made his way towards Firekeep, the last free corner of the land. However, when Darkwolf finally killed Nekron atop of the skull tower, Nekron's death throes caused Icepeak to cross the river adacent to Firekeep, forcing King Jarol and his men to release a deadly flow of lava, which flooded across the jungle and then finally destroyed Icepeak for good, which collapsed when the lava destroyed its ground structures.
Post-war[]
With Icepeak destroyed in the Battle of Icepeak, Firekeep was now free to take control of what remained.
