Shining ????

Description
Taken from a creature that was out of place in this reality, this object defies simple description. It seems to struggle against classification, an unstable form that ripples against the very fabric of time and space.

If the storm could be captured, distilled and forced into a shape, this is what it might look like. This sample is particularly large - holding it sends the mind shuddering back from endless gulfs that threaten to swallow reality.
