Cavern Raised Floors - Insertable Tiles

These are raised cavern floor tiles for use with Dwarven Forge cavern tiles, OpenForge, Fat Dragon Games, etc. The tops have indented slots made to drop in whatever 2x2 tiles you want, allowing you to put some with flat cavern tiles, pools, stalacmites, stairs, or whatever you want.

The intent is to be able to drop these on top of other (flat) cavern tiles to give some height variation in caverns.

The openings in the top should work fine with any terrain made for about 51mm x 51mm gaming t
