[Deleted] Omega Squad Teemo Skin SmknWdl (NA) submitted about an hour ago in Story & Art So the new teemo skin coming out needs some lore behind it...

In a war stricken Valoran, Teemo has brought out his inner killer... Teemo is known for shutting off his emotions in battle, but he has reached a whole new level since Zaun invaded Bandle city. The Zaunites, funded by Noxus, invented a mind controlling technology that affected most of the yordles in Bandle city. Teemo remained one of the few unaffected, but at a horrible price. He had to turn on some of his own kind that day... killing Tristana and several other of his closest friends that had succumbed to Zaun's creation. That same day, the League of Legends lost its peacekeeping powers. The Voidlings invaded, bringing monsters that were sickeningly deadly, and other unspoken horrors into Runeterra. The Shadow Isles began their assault on the mainland, leaving a trail of death and destruction in their wake. Entire forests were killed off; hollow trees and dead plants were all that remained. Demacian and Noxian hostilities have arisen again, and assorted factions throughout Runeterra are hunkering down and choosing an every man for himself attitude... Teemo and a group of assorted yordles, humans, and other individuals that wish to save what remains of Runeterra formed what is known as the Omega Squad, placing Teemo as their leader. But concerning Teemo's mind... some fear that when the fighting is finished he will never resurface from the cold, calculated, and emotionless yordle he has become.

Ok I know that was really cheesy and lame, and probs really stupid too. But leave your thoughts anyways, as I do think the little guy needs some loving in the lore.

little fan lore about the new teemo skin to story and art... Could someone please tell me what i violated in posting it, as it is quite frustrating that riot games doesnt actually take the time to tell me what i have done wrong in posting an innocent little story about satan himself...
