It got pointed out when I brought up Winterers that the definition of it is people or birds that go to a certain place in winter. which could mean it's a red herring and we're actually going somewhere warm.

There's no guarantee that there is not another shard they attempted to create an Ice calamity with and didn't succeed. Technically there are two known to have had issues with Lightning, and two that had issues with darkness (one is supposedly unaspected but it looks like darkness).
