A/n: This should be your first clue that she had something to do with it. For as grandiose as Ruby Gray likes to be, she also tends to prefer to stay under the radar unless it's one of the specific things that she wanted everyone to know about. So take whatever she says with a grain of salt.
It appeared about seven years ago and resulted in the creation of the VC, creating a kind of boundary around the perpetual swirling vortex.
It's not a tornado, though. Or a proper storm, since it doesn't follow the usual patterns. It might look like a storm, but it's not a storm. And it may or may not do anything other than just look like a storm.

Only From the Side

It does really look like a storm, when viewed from the side. A great column of black and gray cloud, leveling off at about two thousand feet above the ground. Approximately. Not like I measured or anything.
The view from above and below is rather unusual. Instead of the usual galaxy swirl, it forms a series of rings, where the internal rings are known to shift color on occasion. At the center, instead of an eye, there is a fluffy white ball about one hundred meters in diameter.
