Lichling

A cool 2nd edition monster the Lichling, cockroach undead spawned from demiliches that start of at about 6 inches tall and over the course of 100-1000 years grow to sizes of 80 feet long.
Added a couple of desert monsters to the scene, got a Dust Mephit flying in the back an Asahi lizardfolk and a good ol mummy clambering up a sand dune.
