I've been bothered by the disappearance of pdf products due to the ending of the d20 system license. To combat that Identical Games has created the Endangered Races line. It will take open game content and expand upon the material so that it is not lost. The first is the Quasta
, originally from Dragonstar. While writing the product, I thought the creature would work well in the DragonMech world. The product includes notes for using them in a world with steam/clockwork mechs. Along with those suggestions is a new mech, the Skyow-Gwa. The Skyow-Gwa is a tripod design like the invaders in the War of the Worlds.
