EDIT I moved the walls around so that other tiles fit on top more easily.
I wanted to beef up my collection of hexagon tiles to be used with MTG Arena of the Planeswalker (or with heroscape for the old schools out there). This set is themed after ruins and stone paths with walls and pillars.
Check out my other hex terrain:

Stay tuned for more sets to come...
Please let me know if you would like to see other hex tile sets!
