I think this is a shard of something, or someone. It appeared on two places, near Institute of War and near Urtistan, next one is maybe in Plague jungles.

They are certainly not from Taric, they are spiky and not shiny. Void creatures are insectoid mostly so I would ignore them also.

But Skarner... Maybe he has something to do with this?

Time will tell.
