Thanks for the mention Dsurion! Some nice Chasm maps is something I need to get more of. I do have a few Tile sets with a Map or two that contains a chasm, but as for a tile set devoted to their awesomeness, I have not done that yet. I'm all open for suggestions as to what you are looking for in a builder set aimed to recreate this. This set here is a Desert Themed Cave and Dungeon tile set, and it has a two maps with Chasms: https://marketplace.roll20.net/browse/set/1720/edv
... Would a look like this (with a more organic soil color as opposed to desert sand) be something you are looking for? If so I could design a tile set aimed to run along side a Chasm, showing the drop off at one side of the tile and the ground the players walk on on the other, or I could just include more maps with Chasm's like these two maps (25x25_Desert_Cave_7 and 25x25_Desert_Cave_8) but in a normal (not Desert themed) cave set. I am planning to build a few sets like this already, and plan to begin one this week coming, so any input to what exactly you are looking for will be used right away.
