There are good writers, and then there are great writers. Lizard is a great writer, his setting overflows with playable ideas, creative kick-starters (triggers I call them) and engaging discription. The classic SF genre trope of a world city when it gets wrecked -- think Star Wars Episode III and the Imperial planet city cut off and the lights go out -- gets a thoughough workout here with logical extensions of what would happen and some things that aren't logical but wonderfully bizaare you would never think of (the way the energy is kept shut off is both plot point, source of intelligent traps, and big bad wolf to defeat or work with). Although written for HERO system, the background itself is nearly systemless (only a few statblocks here and there) so can be used in any setting. Highly, highly recommended.
