I assembled this 'desert ruins' map using pieces from the larger-sized Iymrith's Lair map--this allows for an easy to use, desert-themed map for any DMs that may have a use for such a thing without having to use the very site-specific arena-themed Lair map.
This one's a freebie! Just a little something extra to tack on to the Iymrith content to make sure we get all we can out of it.
Enjoy!
