Lyngbakr is a type of dwarf planet found in eleven star systems accessible by wormholes at Lutetia. Several hundred frozen ponds are on the surface, along with several hundred thousand cave entrances leading to an underground labyrinth of tunnels. Numerous landings have been made and many samples taken, but no evidence of mining has been found, and nothing to show the surface has been modified, but the strange similarities of the eleven planets indicates they are not naturally formed. No evidence of biological activity has been found. On three occasions, landing encountered instability caused by partial tunnel collapses.
