A Spartan in Westeros (A Song of Ice and Fire X Halo Crossover)

When the Forward Unto Dawn lands in the North, it sets the stage for untold repercussions which will ripple throughout the whole of Westeros. With civil war threatening to tear the land apart, and an entirely more dire threat arising beyond the Wall, John and Cortana take it upon themselves to again protect the whole of mankind; from both it's own demons... and those beyond.
