See the whole series is ‘A Song of Ice and Fire’ which suggests a coming together of the Targaryens (FIRE and Blood) and the Starks (WINTER is coming), yes?
Ok so the Targaryens are represented by a dragon sigil:
and the Starks a direwolf:
So the coming together of these two things has only one logical conclusion:
FALKOR. Falkor the Luck Dragon happens and everything will be right with Westeros.
