I only know she was the only thing I ever wanted. Someone took her away from me and Seven Kingdoms couldn't fill the hole she left behind.

The speaker frames personal loss as something no amount of political power or territorial dominion can compensate for. By contrasting “the only thing I ever wanted” with “Seven Kingdoms,” the line rejects the usual fantasy calculus—crowns, conquest, and legacy—as inadequate substitutes for intimate attachment. The “hole” metaphor emphasizes grief as an enduring absence rather than a wound that closes, suggesting that ambition can be a mask for longing and that rule itself may be experienced as hollow when it is pursued after (or in place of) love. In Martin’s world, where desire and power constantly collide, the quote underscores how private emotions can outscale public triumphs.
