An arid world of sun-baked rock and funnel forests. Life clings to the shores of its four major seas, where forests of multikilometer-high baloon plants and familiar-looking trees thrive. Terrestrial animals move by rolling or floating, while aquatic ones glide through the seas using siphons, cilia, pumps and fins. In the skies, floaters and aerial plankton are abound, straining the amber glow of Penkalep through a green and purple sieve.
