@Riot, A lore question about GoTS Skins.

First off, for those who don't know, there ARE lore related skins. For example, Cutthroat Graves and Cutpurse TF are TF and Graves before Graves ended up in jail. -_- Now my question, are the GoTS skins & Risen Fiddle just there because skins, or are they actually supposed to be there in Shurima? I could easily imagine them being guardians build by ancient Shurimans to guard tombs like Azirs tomb, maybe the one Renekton and Xerath god ''burried'' in. I think it'd be a cool thing to think about whenever playing with one of these skins ^u^
