Winter versus Summer! Light versus Dark!
The Legends say:
The Winter-Lord was King of the realm for many ages. Winter and darkness reigned. The Winter-Lord was cruel and twisted. Under his rule, life perished and death prevailed.
In the morbidity, people were aware of this harsh tyranny.
There was however, one champion of hope. One flower of the fight for freedom. One blossoming spark of light amidst the darkness. She was the Summer-Queen who came to claim her throne, and bring peace and harmony to the realm.
However the Winter-Lord would not give up his dominion without a fight.
