What rare skin-shards have you gotten out of your VS event orbs?

I recently got a skin-shard I hadn't seen before out of an order orb. So I did some research..

The Perseus Pantheon Scandal happened in early 2011

Riot gave Perseus Pantheon, and Pantheon the champion for free to any account that had been inactive for 3 months prior

Players were rightfully outraged riot was giving free content to quitters, so Riot promised to give something to the loyal players

and to this day, that promise has been buried under the dirt, left behind in the dust
