"A beached Filter Chad lays still along the coast of Ovi Subtropical Beach, its exoskeleton now becoming a home to numerous colonies of Ghost Mycostrums which slowly spread across its surface. Around it are the long dead husks of ancient crystal flora - Landfall Groves, Crystal Gazebos, and a Giant Gazebulb - now overrun in patches of various Corcraonach species. With morning, the scavengers will swarm, but for now all is silent along this coastline, as this time of dying takes its toll on the largest of Sagan IV's lifeforms."----
