Contearce is a small planet inhabited by Trolls along with other native species. Its surface is covered in vast deserts and sprawling polar wastelands with a few tropical islands between the two. The planet was only just recently inhabited by Trolls in the last hundred or so sweeps; so, while most traditional Troll customs are still practiced, others are either altered or ignored completely. For example, instead of traditional lusi, Trolls raised on Contearce are reared by native animals and gain some characteristics of their custodians. Contearcian "lusi" select young Trolls by physical appearance; they often chose a Grub that shares certain physical traits such as ear or horn shape.
