We have already seen The Night King's mystical powers in Game Of Thrones. He can create ice spears (such as the one he used to kill Viserion) and freeze a sword until it shatters.

Can he freeze a lake or even a sea to rule over the islands and kill the humans on it?

I know this thought is pretty vague but one could not limit the ambitions of the Night King.

    The wights travel under the frozen lake to retrieve Viserion's corpse, so it's possible that they wouldn't need any special means to cross the sea. They could just walk.

  • @DKu - being in the dry, frozen air is going to have a vastly different impact on dead flesh than being submerged in water. I think walking any distance under water is going to pretty much cause a wight to fall apart. Since the Night King wanted the dragon badly enough, I think he was fine on sacrificing any number of them to take the chains down and attach them to the dragon corpse, but that probably would not work as well if you needed them to fight after such a hike. Which would explain why they stop at water. Apr 29, 2019 at 20:52

If we think logically, he could have come around the wall if he could freeze the sea (shown in red).

enter image description here

I think, with the help of the dragon he captured, he can fly across the ocean.


No, he can't freeze a lake. In the lead-up to killing Viserion, he and his army had to wait patiently for the lake to freeze naturally before they could attack Jon Snow and friends. Had he been able to freeze the lake himself, he likely would have done so, and would've killed everyone on the island before the dragons ever showed up.

    It is entirely possible that the Night King did not freeze the lake on purpose, as he was waiting for the dragons to show up. He would gain very little by massacring the few people on that island, but he gains the means to cross the wall by waiting for the dragon. Furthermore, we have previously seen water freeze instantly before the White Walkers.

    He gains fresh, combat-capable corpses for his army. Besides, does he have any reason to assume that if he waits long enough to kill them, a dragon will show up for him to take?

    @PoloHoleSet This isn't true. Jojen uses greensight, Rickon appears to use greensight, and in the books there are many others such as the Warlocks of Qarth and the Red Priests. The Three-Eyed Raven is special as he seemingly has total control of the power, which appears to come from the weirwood tree, which comes from the Children. The previous Three-Eyed Raven was even straight chillin' with some Children.

    Even simpler: he clearly could have just sniped them all with some ice javelins. He must not have for a particular reason; it was to his advantage to bide his time. Apr 23, 2019 at 19:08
