Use an immersion blender or whisk to blend the yolks and sugar until pale and frothy. Set aside.
In a small sauce pan over medium heat, combine the heavy cream, vanilla, honey and salt. Simmer until the liquid reaches 175 F. Remove from the heat.
Temper in the egg yolk mixture by slowly adding about 2-3 tablespoons of the heavy cream mixture to the egg yolks and whisking until smooth. Return the tempered mixture to the pan with the rest of the heavy cream mixture.
Return the liquid to 175 F, stirring constantly. Remove from the heat and while the liquid is still hot, add the cream cheese, buttermilk and lemon juice. Use the immersion blender or a whisk to blend the liquid until smooth then chill for at least 2-3 hours, until the liquid is no longer warm to the touch.
Meanwhile, in a small bowl, whisk together the brown sugar, melted butter, and flour. Whisk until the brown sugar is crumbly and all of the flour is absorbed.
Separate the crumbles into smaller bowls. Stir the black and blue food coloring into each respective bowl so that the brown sugar crumbles are coated in food coloring. Set aside while you make the rest of the ice cream.
Chop the blue candy melts into small, rough pieces. Set aside.
At this point, the cream mixture should be thick but still very runny. Transfer the chilled cream mix into an ice cream churn. Churn the ice cream until thick and creamy - about 1-2 hours.
Scoop the churned ice cream into a large air tight container. Between scoops, sprinkle in the colored brown sugar crumbles and candy melts. Swirl in additional food coloring, as desired (I used the remaining gel on toothpicks I used to get the gel out of the containers).
Cover the ice cream air tight and let freeze solid - about 8-10 hours.
Just prior to serving, combine the caramel sauce, chocolate sauce and red food coloring to make a 'life blood' sauce. Scoop the ice cream into a chilled bowl and drizzle on the 'life blood' sauce. Enjoy as if Westeros isn't going to be overrun with White Walkers.
