Now i know a lot of it has been retconed or will be. But i am making a D&D game based in the world of LoL so here I am. I can find a few small things on the Institute of war but they are very old. As well as a up to date map of the overall world is hard to find. So if anyone has any info please don't hesitate to post. Hopefully maybe someone at riot will see then and say something.
Well the old lore had this as its map http://vignette4.wikia.nocookie.net/leagueoflegends/images/a/a8/Valoran.jpg/revision/latest?cb=20130823193315&path-prefix=de
However the new canon(the one without the IoW) doesn't have a complete map,the biggest one that we have is likely this one: http://euw.leagueoflegends.com/en/featured/piltover/medarda-heirloom It basically consists of 3 continents,Valoran,Ionia and a 3rd continent with an unknown name(we know shurima is part of it),with Valoran and the third continent being connected at one point where Piltover&Zaun are.
