Runeterra Map Missing Content

Putting together a one-shot or at least a starting area to my League/D&D Conversion. Noticed that the Runeterra map, as amazing it is, is still missing a lot of key locations and information. Namely the Avavrosan Tribe current location (I'm guessing West of Rakelstake along a river) and Noxian territory just looks very empty and lacking in towns. Has anyone started a project with a more detailed version of our Runeterra map?
