[0.80] Pendant Expansion! EXPENSIVE

Can someone tell me what this is? Like, what it has to do with the patch and such.

At first, I thought it was a monster. Come on, live tornados would make an awesome monster. I've always pictured a tornado being an enemy. I could imagine a really interesting party quest where you run out of the burning woods from a tornado (like the witch's treasure event where you jump up and away from the burning chocolate) and somehow fight it in the desolate, broken-down city. (Imagine, flying rock obstacles flying toward the tornado, hitting you would stun you, etc)

But still, it looks WICKED awesome in my opinion.
